Subject: [PATCH 1/2] Add goal argument to ext4_new_inode()

The EA inodes are not linked into any directory since a single directory
per filesystem will cause a bottleneck. Instead a "goal" argument has
been added to the ext4_new_inode() function to help a localized
selection of the EA inode. Since ext4_new_inode() only used the dir
argument to choose the group, we use goal argument to do the same.
