[PATCH 2/4] percpu: remove unnecessary initialization in pcpu_build_alloc_info()

[Sang-Heon Jeon <ekffu200098@gmail.com>]

pcpu_build_alloc_info() initializes nr_groups to 1 and unconditionally
sets it to the number of groups. Nothing uses it in between, so the
initialization has no effect.

Remove unnecessary initialization.

No functional change.
