Subject: [PATCH -next] mvsas: remove set but not used variables 'res_flag'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/scsi/mvsas/mv_init.c: In function 'mvs_ioremap':
drivers/scsi/mvsas/mv_init.c:315:36: warning:
 variable 'res_flag' set but not used [-Wunused-but-set-variable]
  unsigned long res_start, res_len, res_flag, res_flag_ex = 0;

It not used anymore after commit
92b19ff50e8f ("cleanup IORESOURCE_CACHEABLE vs ioremap()")
