RDMA/core: Add signature attrs element for ib_mr structure
This element will describe the needed characteristics for the signature
operation per signature enabled memory region (type IB_MR_TYPE_INTEGRITY).
Also add meta_length attribute to ib_sig_attrs structure for saving the
mapped metadata length (needed for the new API implementation).
