Subject: [PATCH] bluetooth rfcomm: fix section mismatch warning

Introduced by Commit 2f8362afcd2da8b313ec3cc04a50af19d3592972
( Bluetooth: Add __init and __exit marks to RFCOMM )

WARNING: vmlinux.o(.init.text+0x246d1): Section mismatch in reference from the function rfcomm_init() to the function .exit.text:rfcomm_cleanup_ttys()
The function __init rfcomm_init() references
a function __exit rfcomm_cleanup_ttys().
This is often seen when error handling in the init function
uses functionality in the exit path.
The fix is often to remove the __exit annotation of
rfcomm_cleanup_ttys() so it may be used outside an exit section.

This patch removes the __exit annotation from rfcomm_cleanup_ttys to eliminate the warning.
