scsi: ipr: Make ipr_probe_ioa_part2() return void

Convert function ipr_probe_ioa_part2() to return void instead of int since
the current implementation always returns 0 to the caller.  The
transformation also eliminates the dead code when calling
ipr_probe_ioa_part2() function.  Issue identified using returnvar
Coccinelle semantic patch.
