Namhyung Kim 5a23b38412 perf jevents: Fix suspicious code in fixregex() 
[ Upstream commit e62458e3940eb3dfb009481850e140fbee183b04 ]

The new string should have enough space for the original string and the
back slashes IMHO.

Fixes: fbc2844e84038ce3 ("perf vendor events: Use more flexible pattern matching for CPU identification for mapfile.csv")
