Merge branch 'mlxsw-Couple-of-fixes'

Ido Schimmel says:

====================
mlxsw: Couple of fixes

First patch makes sure mlxsw does not ignore user requests to delete FDB
entries that were learned by the device.

Second patch fixes a use-after-free that can be triggered by requesting
a reload via devlink when the previous reload failed.

Please consider both patches for stable. They apply cleanly to both
4.18.y and 4.19.y.
