This patch fixes following cleanup issues:
 - Missing instruction queue free on cleanup. This
   will lead to memory leak.
 - lfs->lfs_num is set to zero before cleanup, which
   will lead to improper cleanup.

Signed-off-by: Bharat Bhushan <bbhushan2@marvell.com>

v1->v2:
 - Instruction queue disable needed to be done before
   unregistering for alog, so keep that as it was before.
