devtmpfs: Convert dirlock to a mutex
devtmpfs has a rw_lock dirlock which serializes delete_path and
create_path.
This code was obviously never tested with the usual set of debugging
facilities enabled. In the dirlock held sections the code calls:
- vfs functions which take mutexes
- kmalloc(, GFP_KERNEL)
In both code pathes the might sleep warning triggers and spams dmesg.
Convert the rw_lock to a mutex. There is no reason why this needs to
be a rwlock.
