regcache: Mark cache dirty if selector register rewrite fails
After a successful cache synchronization, regcache_sync() clears
cache_dirty. If rewriting a selector register later fails, the cache
and hardware become inconsistent while the cache still appears clean.
Update cache_dirty to reflect the cache and hardware state when
selector register rewriting fails.
