patch 9.0.2172: Vim9: compiling :defer may fail

Browse Source 
Problem:  Vim9: compiling :defer may fail
Solution: compile defer, when ctx_skip is not SKIP_YES

compiling defer fails in an if statement with false condition,
so check the ctx_skip value when compiling :defer

fixes:  #13698
closes: #13702
