Fix for bug#37337: Function returns different results
Problem: REGEXP in functions/PSs may return wrong results
due to improper initialization.
Fix: initialize required REGEXP params.

Fix for bug#37337: Function returns different results
prev_regexp is used in the Item_func_regex::regcomp()
to store previous regex and to avoid re-initialization
if given the same pattern.
Shoud be deleted in the Item_func_regex::cleanup() where we
clean up the regexp structure.
