syscall: Implement a convinience function restart_syscall
Currently when we have a signal pending we have the functionality
to restart that the current system call. There are other cases
such as nasty lock ordering issues where it makes sense to have
a simple fix that uses try lock and restarts the system call.
Buying time to figure out how to rework the locking strategy.
