Subject: [PATCH AUTOSEL 4.19 537/671] f2fs: fix error path of f2fs_convert_inline_page()

From: Chao Yu <yuchao0@...wei.com>

[ Upstream commit e8c82c11c93d586d03d80305959527bcac383555 ]

In error path of f2fs_convert_inline_page(), we missed to truncate newly
reserved block in .i_addrs[0] once we failed in get_node_info(), fix it.
