[PATCH -next] userfaultfd: remove set but not used variable 'h'

[YueHaibing]

Fixes gcc '-Wunused-but-set-variable' warning:

mm/userfaultfd.c: In function '__mcopy_atomic_hugetlb':
mm/userfaultfd.c:217:17: warning:
 variable 'h' set but not used [-Wunused-but-set-variable]

It is not used since commit 78911d0e18ac ("userfaultfd: use vma_pagesize
for all huge page size calculation")
