net: macsec: Add endianness annotations in salt struct

This change resolves warning produced by sparse tool as currently
there is a mismatch between normal generic type in salt and endian
annotated type in macsec driver code. Endian annotated types should
be used here.

Sparse output:
warning: restricted ssci_t degrades to integer
warning: incorrect type in assignment (different base types)
expected restricted ssci_t [usertype] ssci
got unsigned int
warning: restricted __be64 degrades to integer
warning: incorrect type in assignment (different base types)
expected restricted __be64 [usertype] pn
got unsigned long long
