f2fs: pass correct iostat type for single node writes

f2fs_write_single_node_folio() takes an io_type argument, but still
passes FS_GC_NODE_IO to __write_node_folio() unconditionally.

This was harmless while the helper was only used by
f2fs_move_node_folio(), whose caller passes FS_GC_NODE_IO. However,
commit fe9b8b30b971 ("f2fs: fix inline data not being written to disk
in writeback path") made f2fs_inline_data_fiemap() call the helper with
FS_NODE_IO for FIEMAP_FLAG_SYNC.

Honor the caller supplied io_type so inline-data FIEMAP sync writeback is
accounted as normal node IO instead of GC node IO, while the GC path
continues to pass FS_GC_NODE_IO explicitly.
