scsi: lpfc: Fix return value of board_mode store routine in case of online failure
On hbacmd reset failure, observing wrong string "nline" in kernel log. On failure, non negative value (1) is returned from sysfs store routine. It is interpreted as count by kernel and store routine is called again with the remaining characters as input. Fix: Return negative error code (-EIO) in case of failure.
