ext4: fix reading leftover inlined symlinks
Since commit 6493792d3299 ("ext4: convert symlink external data block
mapping to bdev"), create new symlink with inline_data is not supported,
but it missing to handle the leftover inlined symlinks, which could
cause below error message and fail to read symlink.
ls: cannot read symbolic link 'foo': Structure needs cleaning
EXT4-fs error (device sda): ext4_map_blocks:605: inode #12: block
2021161080: comm ls: lblock 0 mapped to illegal pblock 2021161080
(length 1)
Fix this regression by adding ext4_read_inline_link(), which read the
inline data directly and convert it through a kmalloced buffer.
