RDMA/mlx5: Fix incorrect MKEY masking

Browse Source 
mkey_mask is __be64 type, while MLX5_MKEY_MASK_PAGE_SIZE is declared as
unsigned long long. This causes to the static checkers errors:

drivers/infiniband/hw/mlx5/umr.c:663:49: warning: invalid assignment: &=
drivers/infiniband/hw/mlx5/umr.c:663:49:    left side has type restricted __be64
drivers/infiniband/hw/mlx5/umr.c:663:49:    right side has type int
