blob: pass NULL or SPDK_BLOBID_INVALID when bserrno != 0

Browse Source 
When an operation fails, we shouldn't pass a handle or
a 'valid' blob ID to the caller's completion function.
The caller *should* ignore it when bserrno != 0, but
it's best to not take that chance.

Fixes #685.

Note: #685 seems to have a broader issue related to
a possibly locked NVMe SSD in the submitter's system.
This only fixes the assert() that was hit.
