[PATCH 04/14] rt2x00: correct address calc for queue private data

[Ivo van Doorn <ivdoorn@gmail.com>]

From: Adam Baker <linux@baker-net.org.uk>

When calculating the offset to add to the queue entry base to get the
individual entry's private data area the base address must be treated
as a char * not a struct queue_entry so we can do byte oriented
pointer arithmetic with it.
