[PATCH] HPFS: missing lock_kernel() in hpfs_readdir()

In 2.5.x, the BKL was pushed from vfs_readdir() into the filesystem
specific functions.  But only the unlock_kernel() made it into the HPFS
code, lock_kernel() got lost on the way.  This rendered the filesystem
unusable.

This adds the missing lock_kernel().  It's been tested by Timo Maier who
also reported the problem earlier today.
