JFFS2: fix race condition in jffs2_lzo_compress()
commit dc8a0843a435b2c0891e7eaea64faaf1ebec9b11 upstream
deflate_mutex protects the globals lzo_mem and lzo_compress_buf. However,
jffs2_lzo_compress() unlocks deflate_mutex _before_ it has copied out the
compressed data from lzo_compress_buf. Correct this by moving the mutex
unlock after the copy.
In addition, document what deflate_mutex actually protects.
