JFFS2: Fix lack of locking in thread_should_wake()

commit b27cf88e9592953ae292d05324887f2f44979433 upstream

The thread_should_wake() function trawls through the list of 'very
dirty' eraseblocks, determining whether the background GC thread should
wake. Doing this without holding the appropriate locks is a bad idea.
