Subject: [PATCH 3.16 233/294] scsi-tgt: fix type conversion warning

3.16.50-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Arnd Bergmann <arnd@...db.de>

In 3.16-stable, we get this warning:

drivers/scsi/scsi_tgt_if.c:289:36: warning: passing argument 1 of 'virt_to_phys' makes pointer from integer without a cast [-Wint-conversion]

The driver was removed in 3.17, so the bug was never fixed, but the code
works correctly and is only lacking a cast to build cleanly on all architectures.

Fixes: 97f78759ea1c ("[SCSI] scsi tgt: scsi target user and kernel communication interface")
