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

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")
