[PATCH 8/9] power: wakeup: Add missing annotation for wakeup_sources_stats_seq_start() and wakeup_sources_stats_seq_stop()

[Jules Irenge <jbi.octave@gmail.com>]

Sparse reports warnings at wakeup_sources_stats_seq_start()
	and wakeup_sources_stats_seq_stop()

warning: context imbalance in wakeup_sources_stats_seq_start()
	- wrong count at exit
context imbalance in wakeup_sources_stats_seq_stop()
	- unexpected unlock

The root cause is the missing annotation at
wakeup_sources_stats_seq_start() and wakeup_sources_stats_seq_stop()

Add the missing  __acquires(&wakeup_srcu) annotation
Add the missing __releases(&wakeup_srcu) annotation
