[PATCH 1/9] sound/oss/btaudio.c: ioremap balanced with iounmap

[Amol Lad <amol@verismonetworks.com>]

ioremap must be balanced by an iounmap and failing to do so can result
in a memory leak.

Tested (compilation only):
- using allmodconfig
- making sure the files are compiling without any warning/error due to
new changes
