rS367627: malloc: retire malloc_last_fail
Summary

The primitive is not very useful as most consumers call malloc with M_WAITOK and plenty of memory comes from zones anyway, finally it only reports a timestamp.

The only consumer is GBDE which phk promised to take care of, this will wait with landing until it happens.

This eliminates a branch and is a minor step towards fast path.
