[PATCH] f2fs: remove unneeded set_cold_node()

From: Chao Yu
Date: Fri Mar 09 2018 - 01:24:40 EST


When setting COLD_BIT_SHIFT flag in node block, we only need to call
set_cold_node() in new_node_page() and recover_inode_page() during
node page initialization. So remove unneeded set_cold_node() in other
places.
