net: netmem: fix skb_ensure_writable with unreadable skbs
skb_ensure_writable should succeed when it's trying to write to the
header of the unreadable skbs, so it doesn't need an unconditional
skb_frags_readable check. The preceding pskb_may_pull() call will
succeed if write_len is within the head and fail if we're trying to
write to the unreadable payload, so we don't need an additional check.
Removing this check restores DSCP functionality with unreadable skbs as
it's called from dscp_tg.
