sfc: fix ef100 RX prefix macro
Macro PREFIX_WIDTH_MASK uses unsigned long arithmetic for a shift of up
to 32 bits, which breaks on 32-bit systems. This did not previously
show up as we weren't using any fields of width 32, but we now need to
access ESF_GZ_RX_PREFIX_USER_MARK.
Change it to unsigned long long.
