[PATCH] drivers: skip build of sub-libs not supporting IOVA mode

[Thomas Monjalon <thomas@monjalon.net>]

If IOVA as PA is disabled and the driver does not support IOVA as VA,
the build of the driver was disabled.
Unfortunately some drivers were building some sub-libraries
(with specific options for vector paths) which were not disabled.

The build parsing of those drivers need to be skipped earlier
to avoid defining the sub-libraries.

Fixes: a986c2b7973d ("build: add option to configure IOVA mode as PA")
Cc: stable@dpdk.org
