Subject: [PATCH v2 0/1] PCI/ERR: fix regression introduced by 6d2c89441571 ("PCI/ERR: Update error status after reset_link()")

- Changes since v1:

 * changed the commit message to clarify what broke post commit 6d2c89441571
 * dropped the misnomer post_reset_status variable in favour of a more natural
   approach that relies on a boolean to keep track of the outcome of reset_link()

After commit 6d2c89441571 ("PCI/ERR: Update error status after reset_link()")
pcie_do_recovery() no longer calls ->slot_reset() in the case of a successful
reset which breaks error recovery by breaking driver (re)initialisation.
