[PATCH -next] scsi: qedi: remove set but not used variables 'cdev' and 'udev'

[Yue Haibing]

From: YueHaibing <yuehaibing@huawei.com>

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

drivers/scsi/qedi/qedi_iscsi.c: In function 'qedi_ep_connect':
drivers/scsi/qedi/qedi_iscsi.c:813:23: warning: variable 'udev' set but not used [-Wunused-but-set-variable]
drivers/scsi/qedi/qedi_iscsi.c:812:18: warning: variable 'cdev' set but not used [-Wunused-but-set-variable]

They are never used since introduction.
