[VPP-2032] moniter interface data is not correct
Description
In vpp 22.02
I get inaccurate results with monitor interface command，tx data is incorrect
DBGvpp# monitor interface local0 interval 10 count 1
rx: 0pps 0bps tx: 2314885530.28Gpps 18446744069.41Gbps
in src/vnet/interface/monitor.c
there use u32，but in format_base10 it expects uword.
This looks out of bounds.
src/vppinfra/std-formats.c:
format_base10 (u8 *s, va_list *va)
{
uword size = va_arg (*va, uword);
src/vnet/interface/monitor.c:
92 vlib_cli_output (
93 vm, "rx: %Upps %Ubps tx: %Upps %Ubps%c", format_base10,
94 (u32) ((vrx[spin].packets - vrx[spin ^ 1].packets) / tsd),
95 format_base10, (u32) ((vrx[spin].bytes - vrx[spin ^ 1].bytes) / tsd),
96 format_base10,
97 (u32) ((vtx[spin].packets - vtx[spin ^ 1].packets) / tsd),
98 format_base10, (u32) ((vtx[spin].bytes - vtx[spin ^ 1].bytes) / tsd));
99 }
