xen/grant-table: Export gnttab_{alloc|free}_pages as GPL

Oleksandr Andrushchenko · jgross1 · commit 6e3cc2a6e259 · 2018-06-19T14:45:27.000+02:00
Only gnttab_{alloc|free}_pages are exported as EXPORT_SYMBOL
while all the rest are exported as EXPORT_SYMBOL_GPL, thus
effectively making it not possible for non-GPL driver modules
to use grant table module. Export gnttab_{alloc|free}_pages as
EXPORT_SYMBOL_GPL so all the exports are aligned.
