[PATCH 5/8] scsi: sim710: Remove unused variable 'err' from sim710_init()

[Lee Jones <lee.jones@linaro.org>]

Take the opportunity to rework the comment a little.

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

 drivers/scsi/sim710.c: In function ‘sim710_init’:
 drivers/scsi/sim710.c:216:6: warning: variable ‘err’ set but not used [-Wunused-but-set-variable]
