s390/pci: add missing EX_TABLE entries to __pcistg_mio_inuser()/__pcilg_mio_inuser()

commit 9fae7961f3bb6c20db54903302a6cb45ca6880cf upstream.

For some exception types the instruction address points behind the
instruction that caused the exception. Take that into account and add
the missing exception table entry.
