Subject: [PATCH] [XTENSA] Add missing a2 register restore in register spill
 routine

Register a2 is saved in depc but wasn't getting restored before
returning from _spill_registers when there weren't any registers
to spill. The mask to cut the top bit from the rotated WINDOWMASK
register was also one bit short.
