net: Make table id type u32

A number of VRF patches used 'int' for table id. It should be u32 to be
consistent with the rest of the stack.

Fixes:
4e3c89920cd3a ("net: Introduce VRF related flags and helpers")
15be405eb2ea9 ("net: Add inet_addr lookup by table")
30bbaa1950055 ("net: Fix up inet_addr_type checks")
021dd3b8a142d ("net: Add routes to the table associated with the device")
dc028da54ed35 ("inet: Move VRF table lookup to inlined function")
f6d3c19274c74 ("net: FIB tracepoints")
