vfio/pci: Handle subsystem realpath() returning NULL

Fix error reported by Coverity where realpath can return NULL,
resulting in a segfault in strcmp().  This should never happen given
that we're working through regularly structured sysfs paths, but
trivial enough to easily avoid.

Fixes: 238e91728503 ("vfio/ccw/pci: Allow devices to opt-in for ballooning")
