[PATCH v2 1/6] kcov: Use unsigned int for kcov_start() mode parameter

[Karl Mehltretter <kmehltretter@gmail.com>]

task_struct::kcov_mode usually holds an enum kcov_mode value, but it can
also carry flag bits such as KCOV_IN_CTXSW, so the field is unsigned int.

kcov_remote_softirq_stop() passes the saved raw value through
kcov_start()'s enum kcov_mode parameter before kcov_start() stores it
back into the unsigned int field. The parameter type therefore does not
match the values it receives.

Type the parameter unsigned int, like the field and the saved copy. No
functional change.
