selftests: mptcp: diag: fix bash warnings on older kernels
Since the 'Fixes' commit mentioned below, the command that is executed
in __chk_nr() helper can return nothing if the feature is not supported.
This is the case when the MPTCP CURRESTAB counter is not supported.
To avoid this warning ...
./diag.sh: line 65: [: !=: unary operator expected
... we just need to surround '$nr' with double quotes, to support an
empty string when the feature is not supported.
Fixes: 81ab772819da ("selftests: mptcp: diag: check CURRESTAB counters")
