RDMA/bnxt_re: Remove unpaired rtnl unlock in bnxt_re_dev_init()

Browse Source 
[ Upstream commit a036ad0883 ]

The fixed commit removes all rtnl_lock() and rtnl_unlock() calls in
function bnxt_re_dev_init(), but forgets to remove a rtnl_unlock() in the
error handling path of bnxt_re_register_netdev(), which may cause a
deadlock. This bug is suggested by a static analysis tool.

Fixes: c2b777a959 ("RDMA/bnxt_re: Refactor device add/remove functionalities")
