Subject: [PATCH] vfio: fix enabled check on error

[ upstream commit 7b74a6e0b638ce69b9d03367ce85258e0da19807 ]

rte_eal_check_module() might return -1, which would have been a
"not false" condition for mod_available. Fix that to only report
vfio being enabled if rte_eal_check_module() returns 1.

Fixes: 221f7c220d6b ("vfio: move global config out of PCI files")
