The format used for formatting SYSFS_FLAG_FW_SEL_BOOT creates the
following warning:

drivers/scsi/qedi/qedi_main.c:2259:35: warning: format specifies type
'char' but the argument has type 'int' [-Wformat]
                   rc = snprintf(buf, 3, "%hhd\n",
SYSFS_FLAG_FW_SEL_BOOT);

Fix this to cast the constant as an u8 since the intention is to print
it via sysfs as a byte.

That was what v1 did here:

however Manish seemed to want that flag to be printed as a byte I am 
fine either way.
