Matthew Wilcox (Oracle) 9efdc0081c ida: Fix crash in ida_free when the bitmap is empty 
[ Upstream commit af73483f4e8b6f5c68c9aa63257bdd929a9c194a ]

The IDA usually detects double-frees, but that detection failed to
consider the case when there are no nearby IDs allocated and so we have a
NULL bitmap rather than simply having a clear bit.  Add some tests to the
test-suite to be sure we don't inadvertently reintroduce this problem.
Unfortunately they're quite noisy so include a message to disregard
the warnings.
