scsi: mvsas: Move 'core_nr' inside #ifdef and remove unused variable 'res_flag'

Browse Source 
Only declare 'core_nr' if its conditions for use are met.

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

 drivers/scsi/mvsas/mv_init.c: In function ‘mvs_interrupt’:
 drivers/scsi/mvsas/mv_init.c:180:6: warning: variable ‘core_nr’ set but not used [-Wunused-but-set-variable]
 drivers/scsi/mvsas/mv_init.c: In function ‘mvs_ioremap’:
 drivers/scsi/mvsas/mv_init.c:302:36: warning: variable ‘res_flag’ set but not used [-Wunused-but-set-variable]

[mkp: applied follow-up fixup patch]
