This patch fixes below Smatch reported issues:

 1. lpfc_hbadisc.c:3020 lpfc_mbx_cmpl_fcf_rr_read_fcf_rec()
    error: uninitialized symbol 'vlan_id'.

 2. lpfc_hbadisc.c:3121 lpfc_mbx_cmpl_read_fcf_rec()
    error: uninitialized symbol 'vlan_id'.

 3. lpfc_init.c:335 lpfc_dump_wakeup_param_cmpl()
    warn: always true condition '(prg->dist < 4) => (0-3 < 4)'

 4. lpfc_init.c:2419 lpfc_parse_vpd()
    warn: inconsistent indenting.

 5. lpfc_init.c:13248 lpfc_sli4_enable_msi()
    warn: 'phba->pcidev->irq' 2147483648 can't fit into 65535
    'eqhdl->irq'

 6. lpfc_debugfs.c:5300 lpfc_idiag_extacc_avail_get()
    error: uninitialized symbol 'ext_cnt'

 7. lpfc_debugfs.c:5300 lpfc_idiag_extacc_avail_get()
    error: uninitialized symbol 'ext_size'

 8. lpfc_vmid.c:248 lpfc_vmid_get_appid()
    warn: sleeping in atomic context.

 9. lpfc_init.c:8342 lpfc_sli4_driver_resource_setup()
    warn: missing error code 'rc'.

10. lpfc_init.c:13573 lpfc_sli4_hba_unset()
    warn: variable dereferenced before check 'phba->pport' (see
    line 13546)

11. lpfc_auth.c:1923 lpfc_auth_handle_dhchap_reply()
    error: double free of 'hash_value'

Fixes:

 1. Initialize vlan_id to LPFC_FCOE_NULL_VID.

 2. Initialize vlan_id to LPFC_FCOE_NULL_VID.

 3. prg->dist is a 2 bit field. Its value can only be between 0-3.
    Remove redundent check 'if (prg->dist < 4)'.

 4. Fix inconsistent indenting.  Moved logic into helper function
    lpfc_fill_vpd().

 5. Define 'eqhdl->irq' as int value as pci_irq_vector() returns int.
    Also, check for return value of pci_irq_vector() and log message in
    case of failure.

 6. Initialize 'ext_cnt' to 0.

 7. Initialize 'ext_size' to 0.

 8. Use alloc_percpu_gfp() with GFP_ATOMIC flag.

 9. 'rc' was not updated when dma_pool_create() fails.  Update 'rc =
     -ENOMEM' when dma_pool_create() fails before calling goto statement.

10. Add check for 'phba->pport' in lpfc_cpuhp_remove().

11. Initialize 'hash_value' to NULL, same like 'aug_chal' variable.
