Subject: [PATCH] ext4: Remove duplicate definition of ext4_xattr_ibody_inline_set()

ext4_xattr_ibody_inline_set() & ext4_xattr_ibody_set() have the exact
same definition. Hence remove ext4_xattr_ibody_set() and all it's call
references. Convert the callers of it to call ext4_xattr_ibody_inline_set()
instead.
