rpcrdma: Always release the rpcrdma_device's xa_array
[ Upstream commit 63a81588cd2025e75fbaf30b65930b76825c456f ]
Dai pointed out that the xa_init_flags() in rpcrdma_add_one() needs
to have a matching xa_destroy() in rpcrdma_remove_one() to release
underlying memory that the xarray might have accrued during
operation.
