Revert "selinux: reject a permission value exceeding the class permission count"

This reverts commit 9b46fba7528f58ca09eac67ec7d474ff1e9af066.

The stable pick applied the nprim bound after symtab_insert() because
the upstream context (the SEL_VEC_MAX check from commit 18fa21f10d00
"selinux: more strict policy parsing") does not exist in this tree.
On that error path perm_destroy() frees a key/datum pair that is
already linked into the symtab, leading to a double free when the
failed policydb is torn down.

Drop it here; it is re-applied later in this series in its upstream
form, after its strict-parsing prerequisite.
