arch: arm64: Disable infinite recursion warning for discard_table

Browse source 
This commit selectively disables the infinite recursion warning
(`-Winfinite-recursion`), which may be reported by GCC 12 and above,
for the `disable_table` function because no actual infinite recursion
will occur under normal circumstances.
