Subject: [PATCH 00/39] drop null test before destroy functions

Recent commits to kernel/git/torvalds/linux.git have made the following
functions able to tolerate NULL arguments:

kmem_cache_destroy (commit 3942d29918522)
mempool_destroy (commit 4e3ca3e033d1)
dma_pool_destroy (commit 44d7175da6ea)

These patches remove the associated NULL tests for the files that I found
easy to compile test.  If these changes are OK, I will address the
remainder later.
