LoongArch: Get frame info in unwind_start() when regs is not available

Browse source

[ Upstream commit 429a9671f2 ]

At unwind_start(), it is better to get its frame info here rather than
get them outside, even we don't have 'regs'. In this way we can simply
use unwind_{start, next_frame, done} outside.
