Documentation: PCI: Tidy error recovery doc's PCIe nomenclature

Commit 11502fe ("Documentation: PCI: Tidy AER documentation")
replaced the terms "PCI-E", "PCI-Express" and "PCI Express" with "PCIe"
in the AER documentation.

Do the same in the documentation on PCI error recovery.  While at it,
add a missing period and a missing blank.
