RDMA/mlx4: Make check for invalid flags stricter

Browse source

[ Upstream commit d64b1ee12a ]

This code is trying to ensure that only the flags specified in the list
are allowed.  The problem is that ucmd->rx_hash_fields_mask is a u64 and
the flags are an enum which is treated as a u32 in this context.  That
means the test doesn't check whether the highest 32 bits are zero.
