[PATCH] scsi: bsg: drop needless assignment in scsi_bsg_sg_io_fn()

[Lukas Bulwahn <lukas.bulwahn@gmail.com>]

Commit ce70fd9a551a ("scsi: core: Remove the cmd field from struct
scsi_request") refactored scsi_bsg_sg_io_fn(), so that it does not
allocate directly and hence does not return -ENOMEM in its error case.
That makes a remaining assignment of -ENOMEM to the return variable
needless.

Drop this needless assignment in scsi_bsg_sg_io_fn().

No functional change. No change in resulting object code.
