ANDROID: mthp: Prevent TAO non-movable allocations from movable zone

aosp/I30ac33034f0ff697a4330ef752babf94d4e234f5 removed the ability to
allocate non-movable __GPF_COMP allocations from TAO zones as they
could fallback to the movable-zone; causing various issues.

This was reintroduced by aosp/I2fdfc4df8b03daa96fd6c2c8c6630d26a8509ad0
iff the movable zone is not enabled; adding additional checks to verify
this.

However the case of movable_node command line parameter was missed; when
this is set memory blocks can be onlined into the movable-zone.

Add a check for !movable_node_is_enabled() to avoid such __GPF_COMP
allocations from TAO (virtual zones) if it's possible that memory
blocks can come online to the movable-zone.
