[PATCH 1/6] USB-BKL: Remove lock_kernel in usbfs update_sb()

[Arnd Bergmann <arnd@arndb.de>]

From: Andi Kleen <ak@linux.intel.com>

The code this is attempting to lock against does not use the BKL,
so it's not needed.

Most likely this code is still broken/racy (Al Viro also thinks so),
but removing the BKL should not make it worse than before.
