[RFC PATCH 2/9] ext4: stop creating inline data for new regular files

Stop setting EXT4_STATE_MAY_INLINE_DATA for newly allocated regular
file inodes.  New files always use block-based storage.  Directories
retain inline data capability as it still provides value for small
directories without the write path complexity.

Existing file inodes with inline data are not affected -- MAY_INLINE_DATA
is still set for them during iget via ext4_find_inline_data_nolock().
