[PATCH 4/4] scsi: hpsa: Move a variable assignment in hpsa_big_passthru_ioctl()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sun, 4 Mar 2018 22:16:05 +0100

Move an assignment for the local variable "sg_used" so that its setting
will only be performed after corresponding memory allocations succeeded
by this function.
