scsi: qla2xxx: Define static symbols

drivers/scsi/qla2xxx/qla_os.c:40:20: warning: symbol 'qla_trc_array'
was not declared. Should it be static?
drivers/scsi/qla2xxx/qla_os.c:345:5: warning: symbol
'ql2xdelay_before_pci_error_handling' was not declared.
Should it be static?

Define qla_trc_array and ql2xdelay_before_pci_error_handling as static to
fix sparse warnings.
