media: staging: rkisp1: stats: replace locks wq_lock, irq_lock with one lock
This patch removes two locks in the rkisp1_stats struct:
- The mutex 'wq_lock' that is used to protect the buffers list 'stat'
- The spin_lock 'irq_lock' that is used to protect the
variable 'is_streaming'
It replaces them with one spin_lock 'lock' that protects
both the buffers list and the 'is_streaming' variable.
In later patch the reading of the statistics will move to
the isr so there will be no need for the mutex 'wq_lock'
