[PATCH 5.12 203/363] block/rnbd-clt: Change queue_depth type in rnbd_clt_session to size_t

[ Upstream commit 80d43cbd46155744ee450d2476ee4fcf2917ae9b ]

The member queue_depth in the structure rnbd_clt_session is read from the
rtrs client side using the function rtrs_clt_query, which in turn is read
from the rtrs_clt structure. It should really be of type size_t.
