Throw any errors before stack changes in trace stitching.

Thanks to doujiang24.

(cherry-picked from commit 3f9389edc)

The Lua stack is changed in the `lj_record_stop`, so if the trace
is aborted, for example, when the `maxsnap` is reached, and an
error is thrown from there, the execution continues with an
unbalanced stack.

Since the only error that is thrown from the `lj_record_stop`
with modified stack is `LJ_TRERR_SNAPOV`, this patch adds a
check for snapshot overflow to the `recff_stitch`.
