[mini] Don't assert on MONO_PATCH_INFO_GC_SAFE_POINT_FLAG if coop is …

…disabled (mono/mono#9974)

If an AOT library is loaded that was compiled with safepoints, but currently
we're running with preemptive suspend (e.g. MONO_THREADS_SUSPEND=preemptive is
set), don't assert.  `mono_polling_required` will always be false, so the
safepoint will be ignored.

Fixes mono/mono#9947
