This small fix prepares the CN20K inline security receive paths for mbuf
layouts larger than 255 bytes.
The affected code recovers a packet mbuf by subtracting the size of
struct rte_mbuf from a pointer stored in completion metadata. Keeping
that size in an 8-bit local variable makes the recovery sensitive to
future mbuf layout growth. The patch widens the local size variable
without changing the surrounding fast-path logic.
The issue was found while preparing an unrelated mbuf layout extension.
