Subject: [PATCH] f2fs: avoid wrong f2fs_bug_on when truncating inline_data

This patch removes wrong f2fs_bug_on in truncate_inline_inode.

When there is no space, it can happen a corner case where i_isze is over
MAX_INLINE_SIZE while its inode is still inline_data.

The scenario is
 1. write small data into file #A.
 2. fill the whole partition to 100%.
 3. truncate 4096 on file #A.
 4. write data at 8192 offset.
  --> f2fs_write_begin
    -> -ENOSPC = f2fs_convert_inline_page
    -> f2fs_write_failed
      -> truncate_blocks
        -> truncate_inline_inode
	  BUG_ON, since i_size is 4096.
