ANDROID: sdcardfs: Use d_invalidate instead of drop_recurisve

drop_recursive did not properly remove stale dentries.
Instead, we use the vfs's d_invalidate, which does the proper cleanup.

Additionally, remove the no longer used drop_recursive, and
fixup_top_recursive that that are no longer used.
