ext4: Limit number of links that can be created by ext4_link()

Browse Source 
(cherry picked from commit b05ab1dc3795e6f997fb0d34f38fce5012533c3e)

In ext4_link we need to check using EXT4_LINK_MAX, and not
EXT4_DIR_LINK_MAX(), since ext4_link() is creating hard links of
regular files, and not directories.
