NFS: Clean up address comparison in __nfs_find_client()
The address comparison in the __nfs_find_client() function is deceptive. It uses a memcmp() to check a pair of u32 fields for equality. Not only is this inefficient, but usually memcmp() is used for comparing two *whole* sockaddr_in's (which includes comparisons of the address family and port number), so it's easy to mistake the comparison here for a whole sockaddr comparison, which it isn't. So for clarity and efficiency, we replace the memcmp() with a simple test for equality between the two s_addr fields. This should have no behavioral effect.
