Subject: [PATCH] net: enetc: Use pci_release_region() to release some resources

Some resources are allocated using pci_request_region().
It is more straightforward to release them with pci_release_region().

Fixes: 231ece36f50d ("enetc: Add mdio bus driver for the PCIe MDIO endpoint")

Signed-off-by: Christophe JAILLET <christophe.jaillet@...adoo.fr>

This patch is speculative, mainly based on the inconsistency between some
function's names.
Using pci_request_mem_regions() would also have things look consistent.

Review with care.
