[PATCH] reiserfs: Force type conversion in xattr_hash

[Bharath Vedartham <linux.bhar@xxxxxxxxx>]

This patch fixes the sparse warning:

fs/reiserfs//xattr.c:453:28: warning: incorrect type in return
expression (different base types)
fs/reiserfs//xattr.c:453:28:    expected unsigned int
fs/reiserfs//xattr.c:453:28:    got restricted __wsum
fs/reiserfs//xattr.c:453:28: warning: incorrect type in return
expression (different base types)
fs/reiserfs//xattr.c:453:28:    expected unsigned int
fs/reiserfs//xattr.c:453:28:    got restricted __wsum

csum_partial returns restricted integer __wsum whereas xattr_hash
expects a return type of __u32.
