File-level compression fallback is control flow, not a real error.
Return an erofs-specific status code for it instead of overloading
-ENOSPC, which can also report real space failures.
Keep the global compression context reusable for that fallback while
preserving the fatal state for real errors.

is full")

hmmm, the naming is not quite good, I will think out a
new name and manually change it.
