[f2fs-dev] [PATCH] f2fs: fix to avoid accessing uninitialized field of inode page in is_alive()

If inode is newly created, inode page may not synchronize with inode cache, so fields like .i_inline or .i_extra_isize could be wrong, in below call path, we may access such wrong fields, result in failing to migrate valid target block. - gc_data_segment - is_alive - datablock_addr -
