vfs_exports: Tighten bounds and assert consistency of numsecflavors

We know the value must be greater than 0 and less than MAXSECFLAVORS.

Reject values outside this range in the initial check in vfs_export and add
KASSERTs in the later consumers.

Also check that we are called with one of either MNT_DELEXPORT or MNT_EXPORTED
set.
