This follows the scheme of used in the wc by introducing a
ibv_wc_read_invalidated_rkey to access the host endian
invalidated_rkey value with proper annotations.
This is just an inline wrapper to allow sparse to work sensibly,
not really a good reason to add another driver entry point.
Fixes: 32186550 ("verbs: Add be annotations to public headers")
