scsi: lpfc: Ensure variable has the same stipulations as code using it

Browse source 
'pg_addr' is only used when CONFIG_X86 is defined.  So only declare it if
CONFIG_X86 is defined.

Fixes the following W=1 kernel build warning(s):

 drivers/scsi/lpfc/lpfc_sli.c: In function ‘lpfc_wq_create’:
 drivers/scsi/lpfc/lpfc_sli.c:15813:16: warning: unused variable ‘pg_addr’ [-Wunused-variable]
 15813 | unsigned long pg_addr;
 | ^~~~~~~
