[ Upstream commit c46fa8911b17e3f808679061a8af8bee219f4602 ]
Error path of rtrs_clt_open() calls free_clt(), where free_permit is
called. This is wrong since error path of rtrs_clt_open() does not need
to call free_permit().
Also, moving free_permits() call to rtrs_clt_close(), makes it more
aligned with the call to alloc_permit() in rtrs_clt_open().
Fixes: 6a98d71daea1 ("RDMA/rtrs: client: main functionality")
