s390/sysinfo: Add context analysis attributes

Browse source

Add context analysis attributes to service_level_start() and
service_level_stop() to specify that those functions only
acquire or release a lock.

Addresses the following warnings:

arch/s390/kernel/sysinfo.c:331:1: warning: rw_semaphore 'service_level_sem' is still held at the end of function
arch/s390/kernel/sysinfo.c:329:2: note: rw_semaphore acquired here
  329 |         down_read(&service_level_sem);
arch/s390/kernel/sysinfo.c:340:2: warning: releasing rw_semaphore 'service_level_sem' that was not held
  340 |         up_read(&service_level_sem);
