Petar Jovanovic a81ca9f338 Restore unwind regs structure if VG_(use_CF_info) fails on MIPS. ...

If VG_(use_CF_info) fails to find the next frame using loaded debug symbols, it
will still change the data in uregs. Thus, we need to have uregs_copy before
calling VG_(use_CF_info), and restore uregs if the call returns wrong data.
This fixes drd/tests/tc04_free_lock on MIPS.
