tls: fix RX desync on overlapping skbs
The TCP receive queue can hold adjacent skbs whose sequence ranges
overlap. The tls fast-path reads the record header with skb_copy_bits()
by byte offset, which assumes skbs do not overlap, so a header split
across the overlap is misread and the connection aborts
(-EMSGSIZE/-EINVAL). tls_strp_check_queue_ok() detects such overlaps but
only ran after the header was parsed, never covering the header itself.
Observed with parallel kTLS connections on:
- ConnectX-7 + IPsec crypto offload + GRO
- VirtIO (8 queues) + GRO
Fixes: 84c61fe1a75b ("tls: rx: do not use the standard strparser")
