[PATCH] advansys: Remove redundant assignment to err and n_q_required

[Jiapeng Chong]

Variable err and n_q_required is set to '-ENOMEM' and '1', but they are
either overwritten or unused later on, so these are redundant assignments
that can be removed.

Clean up the following clang-analyzer warning:

drivers/scsi/advansys.c:11235:2: warning: Value stored to 'err' is never
read [clang-analyzer-deadcode.DeadStores].

drivers/scsi/advansys.c:8091:2: warning: Value stored to 'n_q_required'
is never read [clang-analyzer-deadcode.DeadStores].

drivers/scsi/advansys.c:11484:2: warning: Value stored to 'err' is never
read [clang-analyzer-deadcode.DeadStores].
