win32: SGR emulation: minor fixup on invalid sequence 

This fixes two issues with invalid value after 38/48:
- It was not detected correctly and ended up skipping 4 instead of 0.
- The intent was to skip 0, but it's better to skip the rest.

Behavior with valid 2/5 after 38/48 was correct and is unaffected.
