Subject: [PATCH 5.3 037/163] RDMA/core: Fix an error handling path in res_get_common_doit()

From: Christophe JAILLET <christophe.jaillet@...adoo.fr>

[ Upstream commit ab59ca3eb4e7059727df85eee68bda169d26c8f8 ]

According to surrounding error paths, it is likely that 'goto err_get;' is
expected here. Otherwise, a call to 'rdma_restrack_put(res);' would be
missing.

Fixes: c5dfe0ea6ffa ("RDMA/nldev: Add resource tracker doit callback")
