Blobstore default cluster size is currently 4MiB,
but default lvol cluster size overrides it to 1GiB.
Additionally add -c flag in lvol tests to set cluster
size for tests.
1GiB was fine without thin provisioning, but we do not
want to allocate and copy 1GiB of data for newly allocated
clusters on thin provisioned logical volumes.
Note that 4MiB is same as default for Linux LVM.
lvol test case 601 had to be modified to create a malloc
LUN less than size of default cluster size. This test is
supposed to fail - without the change here, creating the
lvolstore would work, but the script still considered it a
PASS. Defer fixing that to a separate patch - for now just
keep the same test process.

The spdk_json_decode_array() function previously tried to check whether
the array would fit into the provided number of output elements
(max_size) before decoding; however, the check was incorrectly comparing
the total number of nested JSON values in the array rather than just the
count of top-level array elements.
Rather than doing the check up front (which can't be done without
modifying the way array lengths are stored in spdk_json_value), just
check if we have reached the end of the 'out' array on each iteration of
the decoding loop.
Fixes GitHub issue #232.
