[PATCH 18/62] bnxt_en: Fix bnxt_dl_reload_up()

[Bart Van Assche <bvanassche@acm.org>]

bnxt_dl_reload_down() calls rtnl_lock() and netdev_lock() if it returns
0. Hence, bnxt_dl_reload_up() should invoke the corresponding unlock
calls. This issue has been detected by the clang thread-sanitizer.
Compile-tested only.
