f2fs: avoid to allocate when inline_data was written
The sceanrio is like this. inline_data i_size page write_begin/vm_page_mkwrite X 30 dirty_page X 30 write to #4096 position X 30 get_dnode_of_data wait for get_dnode_of_data O 30 write inline_data O 30 get_dnode_of_data O 30 reserve data block .. In this case, we have #0 = NEW_ADDR and inline_data as well. We should not allow this condition for further access. Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
