scsi: qedf: Remove set but not checked variable 'tmp'

Browse Source 
Looks like the return value of readw() has never been checked.

Fixes the following W=1 kernel build warning(s):

 drivers/scsi/qedf/qedf_main.c: In function ‘__qedf_probe’:
 drivers/scsi/qedf/qedf_main.c:3203:6: warning: variable ‘tmp’ set but not used [-Wunused-but-set-variable]
