Subject: staging: rtl8192e: fix 2 byte alignment of register BSSIDR.

From: Malcolm Priestley <tvboxspy@gmail.com>

commit 867510bde14e7b7fc6dd0f50b48f6753cfbd227a upstream.

BSSIDR has two byte alignment on PCI ioremap correct the write
by swapping to 16 bits first.

This fixes a problem that the device associates fail because
the filter is not set correctly.
