Don't try to read GPIOs when no device path

For certain PGOOD faults, the code may try to read a GPIO off of an IO
expander to further isolate the error.  If there was a problem with the
device driver detecting that IO expander, then the code was running down
a path where it would still try to read that IO expander, but using an
empty device path which would just generate extra error traces in the
journal.  Avoid this by checking for this empty path and then not
reading those GPIOs.
