RDMA/uverbs: Add empty rdma_uattrs_has_raw_cap() declaration

Browse Source 
[ Upstream commit 98269398c0 ]

The call to rdma_uattrs_has_raw_cap() is placed in mlx5 fs.c file,
which is compiled without relation to CONFIG_INFINIBAND_USER_ACCESS.

Despite the check is used only in flows with CONFIG_INFINIBAND_USER_ACCESS=y|m,
the compilers generate the following error for CONFIG_INFINIBAND_USER_ACCESS=n
builds.

>> ERROR: modpost: "rdma_uattrs_has_raw_cap" [drivers/infiniband/hw/mlx5/mlx5_ib.ko] undefined!
