Thomas Gleixner a51a327f3b locking/rtmutex: Clean up signal handling in __rt_mutex_slowlock() ...

The signal handling in __rt_mutex_slowlock() is open coded.

Use signal_pending_state() instead.

Aside of the cleanup this also prepares for the RT lock substituions which
require support for TASK_KILLABLE.
