[dpdk-stable] [PATCH] test/eal: do not scan PCI devices for memory tests

[David Marchand <david.marchand@redhat.com>]

The memory tests currently check that, for normal mode (not legacy mode),
there is no memory left behind when exiting.

The problem is that if a ethdev port is allocated when scanning pci
devices (even if the driver probe fails like when you have a virtio
management interface attached to the kernel), on exit, dpdk won't free
the associated memory since ethdev never frees the ethdev memzone.

Workaround this by disabling pci scan.

Fixes: 651cc78f83b5 ("test: fix hugepage file handling in EAL flags autotest")
Fixes: 690fd3577e90 ("test/eal: add cases for in-memory and single-file-segments")
