BUG/MINOR: resolvers: Use resolver's lock in resolv_srvrq_expire_task()

The commit dcac41806 ("BUG/MEDIUM: resolvers: Add a task on servers to check
SRV resolution status") introduced a type. In resolv_srvrq_expire_task()
function, the resolver's lock must be used instead of the resolver itself.

This patch must be backported with the patch above (at least as far as 2.2).
