Subject: [PATCH] befs/linuxvfs: remove unneeded initialization

res is initialized to 0 in befs_get_block() but this value will be
overwritten before it is used.

Hi,

Saw this small issue while reading the code. BeFS is very interesting, and
reading this code is very educational after reading Dominic Giampaolo's book.

Will continue reading and send more fixes if I see any.

Thanks,
Luis
