[PATCH mptcp-next v7 4/9] mptcp: remove redundant orig_offset in carve_data_frag

From: Geliang Tang <[email protected]>

mptcp_carve_data_frag() already receives struct page_frag via its 'pfrag'
parameter, making the separate 'orig_offset' parameter redundant since it
merely duplicates pfrag->offset.

Simplify the function signature by removing this unnecessary parameter
and directly accessing the offset from struct pfrag internally.
