Subject: hugetlb: initialize variable to avoid compiler warning
Date: Fri, 16 Dec 2022 14:45:07 -0800

With the gcc 'maybe-uninitialized' warning enabled, gcc will produce:

  mm/hugetlb.c:6896:20: warning: `chg' may be used uninitialized

This is a false positive, but may be difficult for the compiler to
determine.  maybe-uninitialized is disabled by default, but this gets
flagged as a 0-DAY build regression.

Initialize the variable to silence the warning.
