David Rientjes 91dfd98216 crypto: ccp - Avoid page allocation failure warning for SEV_GET_ID2 
For SEV_GET_ID2, the user provided length does not have a specified
limitation because the length of the ID may change in the future.  The
kernel memory allocation, however, is implicitly limited to 4MB on x86 by
the page allocator, otherwise the kzalloc() will fail.

When this happens, it is best not to spam the kernel log with the warning.
Simply fail the allocation and return ENOMEM to the user.

Fixes: d6112ea0cb ("crypto: ccp - introduce SEV_GET_ID2 command")
