[PATCH] fs/buffer: Remove the initialization of variables bh_{accounting, lrus}

From: Kaitao Cheng
Date: Fri Apr 17 2020 - 12:20:48 EST


The static global variables will be automatically initialized to 0,
and we do not need to manually initialize to 0. So remove the
initialization of variable bh_{accounting, lrus}.
