scsi: efct: Fix possible memleak in efct_device_init()
[ Upstream commit
bb0cd225dd37df1f4a22e36dad59ff33178ecdfc ]
In efct_device_init(), when efct_scsi_reg_fc_transport() fails,
efct_scsi_tgt_driver_exit() is not called to release memory for
efct_scsi_tgt_driver_init() and causes memleak:
unreferenced object 0xffff8881020ce000 (size 2048):
comm "modprobe", pid 465, jiffies
