blob: pass correct op to spdk_bs_user_op_alloc in iov case

Browse Source 
At some point this parameter may have been a bool, but it's
not now - so we need to explicitly pass SPDK_BLOB_READV or
SPDK_BLOB_WRITEV.

Otherwise we end up trying to write the iovec array as the
data buffer when executing this operation later - since we
passed "false" which is treated as 0 which is
SPDK_BLOB_WRITE (not SPDK_BLOB_WRITEV).

Fixes issue #603.
