Fix issue introduced by commit: 97a5221 "net/mlx4_core: pass
pci_device_id.driver_data to __mlx4_init_one during reset".

pci_match_id() just match the static pci_device_id, which may return NULL if
someone binds the driver to a device manually using
/sys/bus/pci/drivers/.../new_id.

This patch wrap up a helper function __mlx4_remove_one() which does the tear
down function but preserve the drv_data. Functions like
mlx4_pci_err_detected() and mlx4_restart_one() will call this one with out
releasing drvdata.

Tested on ConnectX-3.

Please resubmit this when the net-next tree opens back up, thanks.

Dave, this patch is for net, since it fixes an issue in the current code (actually it relates to a patch that was merged after 3.14-rc7, so it would eventually might go to -stable too). The author wasn't very familiar with the exact differences/nature of net vs. net-next, so it might created some confusion here, I'v
sent him few private notes to explain how things go...

Or.
