[PATCH][2.6] HPFS: missing lock_kernel() in hpfs_readdir()

[Rene Scharfe <l.s.r@web.de>]

Hi Linus,

recently 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.

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

Please apply.

Thanks,
René
