mlxsw: spectrum_fid: Fix incorrect local port type
Local port is a 10-bit number, but it was mistakenly stored in a u8,
resulting in firmware errors when using a netdev corresponding to a
local port higher than 255.
Fix by storing the local port in u16, as is done in the rest of the
code.
Fixes: bf73904f5fba ("mlxsw: Add support for 802.1Q FID family")
