xmalloc_tlsf: Fall back to xmalloc_whole_pages() if xmem_pool_alloc() fails.
This was happening for xmalloc request sizes between 3921 and 3951
bytes. The reason being that xmem_pool_alloc() may add extra padding
to the requested size, making the total block size greater than a
page.
Rather than add yet more smarts about TLSF to _xmalloc(), we just
dumbly attempt any request smaller than a page via xmem_pool_alloc()
first, then fall back on xmalloc_whole_pages() if this fails.
Based on bug diagnosis and initial patch by John Byrne <john.l.byrne@hp.com>
