[Buildroot] [PATCH v3 08/11] fs/ext2: deprecate BR2_TARGET_ROOTFS_EXT2_EXTRA_INODES option

Soon, the ext{2,3,4} rootfs image will no longer be generated with
genext2fs, but using mke2fs instead which has no support for the extra
inode number option.
So, deprecate the BR2_TARGET_ROOTFS_EXT2_EXTRA_INODES option and
recommend, in lieu, to set the total inode number, taking account of
the extra ones if needed.

+ Buildroot now uses mkfs.ext2/3/4 to generate ext2/3/4 images. So

+ Note that, the number of inodes can still be set and passed to
