[PATCH v2 08/13] btrfs-progs: Fix Wtype-limits warning

[Qu Wenruo]

The only hit is the following code:

                tlv_len = le16_to_cpu(tlv_hdr->tlv_len);

                if (tlv_type == 0 || tlv_type > BTRFS_SEND_A_MAX
                    || tlv_len > BTRFS_SEND_BUF_SIZE) {
                        error("invalid tlv in cmd tlv_type = %hu, tlv_len = 
%hu",
                                        tlv_type, tlv_len);

@tlv_len is u16, while BTRFS_SEND_BUF_SIZE is 64K.
u16 MAX is 64K - 1, so the final check is always false.

Just remove it.
