rpma_mr_get_descriptor - get a descriptor of a memory region

rpma_mr_get_descriptor()  writes  a  network-transferable description of the provided local memory region
       (called 'descriptor'). Once the descriptor is transferred to the other  side  it  should  be  decoded  by
       rpma_mr_remote_from_descriptor()  to  create  a  remote memory region's structure which allows for Remote
       Memory Access. Please see librpma(7) for details.

rpma_mr_get_descriptor() can fail with the following error:

       •  RPMA_E_INVAL - mr or desc is NULL

       The rpma_mr_get_descriptor() function returns 0 on success or a negative error code on failure.
