checksrc: fix regexp for ASSIGNWITHINCONDITION
The regexp looking for assignments within conditions was too greedy and matched a too long string in the case of multiple conditionals on the same line. This is basically only a problem in single line macros, and the code which exemplified this was essentially: do { if((x) != NULL) { x = NULL; } } while(0) ..where the final parenthesis of while(0) matched the regexp, and the legal assignment in the block triggered the warning. Fix by making the regexp less greedy by matching for the tell-tale signs of the if statement ending. Also remove the one occurrence where the warning was disabled due to a construction like the above, where the warning didn't apply when fixed. Closes #4647 Reviewed-by: Daniel Stenberg <daniel@haxx.se>
