Subject: [PATCH] test/ut: initialize spdk_bdev_desc to NULL

This fixes error on scan-build on Fedora 30, which assumes spdk_bdev_open()
is called from non-SPDK thread - failing before allocating spdk_bdev_desc:

bdev_ut.c:1766:17: warning: The left operand of '!=' is a garbage value
        CU_ASSERT(desc != NULL);

This is related to issue #822.
