can-calc-bit-timing: silence "comparison of integer expressions of different signedness" warning 

Silence the "comparison of integer expressions of different
signedness" warning. We want to compile the code as is from the
kernel, including bugs.

| calc-bit-timing/can-calc-bit-timing-v2_6_31.c: In function ‘can_update_spt_v2_6_31’:
| calc-bit-timing/can-calc-bit-timing-v2_6_31.c:51:13: warning: comparison of integer expressions of different signedness: ‘int’ and ‘__u32’ {aka ‘const unsigned int’} [-Wsign-compare]

Fixes: 18eb0ab784 ("can-calc-bit-timing: import bit timing calculation algorithm from v4.8")
Fixes: b777ce2e6d ("can-calc-bit-timing: import bit timing calculation algorithm from v3.18")
Fixes: c1f5dc53ec ("can-calc-bit-timing: import bit timing calculation algorithm from v2.6.31")
