[PATCH] x86: dovetail: Call trap exit code with hard IRQs disabled

mark_trap_exit() should do the reverse operations of mark_trap_entry()
keeping ordering in mind. Especially as oob_trap_unwind() is expecting
hard IRQs to be off.

Seems that this is a long standing issue, so most likely all currently
maintained dovetail branches seem affected.
