UPSTREAM: arm64: mte: Fix double-freeing of the temporary tag storage during coredump

Commit 16decce2 ("arm64: mte: Fix the stack frame size warning in
mte_dump_tag_range()") moved the temporary tag storage array from the
stack to slab but it also introduced an error in double freeing this
object. Remove the in-loop freeing.
