xen/arm: p2m: Flush for every exit paths in apply_p2m_changes

Currently, the TLB is not flushed if an error occured while updating the
stage-2 p2m. However, the TLB will contain stale mappings for any entry
updated so far.

To avoid a such situation, flush on every exit path when the variable
"flush" is set.
