queue_extras: use SPDK_CONTAINEROF

Browse Source 
A couple of the functions inside of the queue_extras file were relying
on an undefined __containerof function. Replace that with
SPDK_CONTAINEROF. Then add an extra check so that when someone includes
this file on FreeBSD, it doesn't throw compiler warnings for the
redefinitions (see our cpp headers test for example).

The argument order for both functions is the same, namely pointer, type,
member.
