[JFFS2] fix race condition in jffs2_lzo_compress()
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.
