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

drivers/scsi/lpfc/lpfc_debugfs.c: In function 'lpfc_debugfs_nvmestat_data':
drivers/scsi/lpfc/lpfc_debugfs.c:780:14: warning:
 variable 'maxch' set but not used [-Wunused-but-set-variable]

debugfs display buffer has be limit to 32 in below for loop,
so this can be removed safely.
