patch 8.0.0307: asan detects a memory error when EXITFREE is defined
Problem: Asan detects a memory error when EXITFREE is defined. (Dominique
Pelle)
Solution: In getvcol() check for ml_get_buf() returning an empty string.
Also skip adjusting the scroll position. Set "exiting" in
mch_exit() for all systems.
