ecryptfs: Bugfix for error related to ecryptfs_hash_buckets

commit a6f80fb7b5986fda663d94079d3bba0937a6b6ff upstream.

The function ecryptfs_uid_hash wrongly assumes that the
second parameter to hash_long() is the number of hash
buckets instead of the number of hash bits.
This patch fixes that and renames the variable
ecryptfs_hash_buckets to ecryptfs_hash_bits to make it
clearer.

Fixes: CVE-2010-2492
