Subject: [PATCH v4 1/2] ext4: remove set 'EXT4_STATE_MAY_INLINE_DATA' flag from ext4_find_inline_data_nolock()

From: Ye Bin <yebin10@...wei.com>

The only caller of ext4_find_inline_data_nolock() that needs setting of
EXT4_STATE_MAY_INLINE_DATA flag is ext4_iget_extra_inode(). In
ext4_write_inline_data_end() we just need to update inode->i_inline_off.
Since we are going to add one more caller that does not need to set
EXT4_STATE_MAY_INLINE_DATA, just move setting of EXT4_STATE_MAY_INLINE_DATA
out to ext4_iget_extra_inode().
