[SCSI] fcoe: remove unnecessary module state check
The check of module state being MODULE_STATE_LIVE is no longer needed for the
individual fcoe transport driver, e.g., fcoe.ko, as sysfs entries now go to
libfcoe now, if it reaches fcoe.ko, it has to be already registered. The module
state check for libfcoe will guard the possible race condition of sysfs being
writable before module_init function is called and after module_exit.
