secvar/backend: fix an integer underflow bug
[ Upstream commit 0c265ace91b9d9ee08e09392a7d4a78a1301a3ab ]
If a declared size is smaller than uuid size, we end up allocating
with an allocation of a 'negative' number, which is a huge 64 bit
number.
This will probably then fail with an OPAL_NO_MEM, but it will be
better to catch it and return OPAL_PARAMETER instead.
