net-sysfs: Use rtnl_trylock in sysfs methods.
The earlier patch to fix the deadlock between a network device going
away and writing to sysfs attributes was incomplete.
- It did not set signal_pending so we would leak ERSTARTSYS to user space.
- It used ERESTARTSYS which only restarts if sigaction configures it to.
- It did not cover store and show for ifalias.
So fix all of these up and use the new helper restart_syscall so we get
the details correct on what it takes.
