Subject: [PATCH 3/5] f2fs: remove unneeded initialization of nr_dirty in dirty_seglist_info

From: Namjae Jeon <namjae.jeon@...sung.com>

Since, the memory for the object of dirty_seglist_info is allocated
using kzalloc - which returns zeroed out memory. So, there is no need
to initialize the nr_dirty values with zeroes.
