eal: fix tailq init for uio and vfio resources

Commit a2348166ea18 ("tailq: move to dynamic tailq") introduced a bug in
uio/vfio resources list init.

These resources list were pointed at through a pointer initialised only once but
too early in the eal init (before tailqs init).

Fix this by "resolving" this pointer when used (which is well after tailqs
init).
