Only import allocationSize for a fuchsia buffer

This has 2 advantages:
1) The importer can be certain the size of the imported memory is at
least what was asked for, so texture reads can't go outside it.
2) We can commit a smaller amount of a larger VMO, which can save time
and increase flexibility.
