Subject: [PATCH 5.10 49/80] RDMA/rtrs-clt: Move free_permit from free_clt to rtrs_clt_close

From: Md Haris Iqbal <haris.iqbal@...os.com>

[ 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().
