test/vfio_user: use 2048MiB static memory size for bdevperf



Previously we use 1024MiB static memory for bdevperf, but it may invoke
DPDK dynamic memory allocation when calling `spdk_zmalloc`, and this
part of new memory region isn't registered to remote target process,
vfio-user like solution is designed for pre-allocated memory, so here
we can increase the static memory size as a workaround.

Also add debug log when testing.

Fix issue #2846.
