ibmvnic: Fix unchecked return codes of memory allocations
[ Upstream commit 7c940b1a5291e5069d561f5b8f0e51db6b7a259a ]
The return values for these memory allocations are unchecked,
which may cause an oops if the driver does not handle them after
a failure. Fix by checking the function's return code.
