[PATCH] tcm/pscsi: Convert struct bio->bi_rw assignment to use REQ_WRITE

["Nicholas A. Bellinger" <nab@linux-iscsi.org>]

From: Nicholas Bellinger <nab@linux-iscsi.org>

Greetings hch and tejun,

This patch updates pscsi_map_task_SG() to use the new .36-rc REQ_WRITE
macro in include/linux/blk_types.h when setting struct bio->bi_rw for
WRITE I/O.  This replaces the legacy (1 << BIO_RW) assignment, for which
the new REQ_WRITE macro expands to:

    #define REQ_WRITE       (1 << __REQ_WRITE)

to match the old BIO_RW assignement.

Thanks!
