vmm_dev: work around a bogus error with gcc 6.3.0
The error is: vmm_dev.c: In function 'alloc_memseg': vmm_dev.c:261:11: error: null argument where non-null required (argument 1) [-Werror=nonnull] Apparently, the gcc is unable to figure out that if a ternary operator produced a non-NULL value once, then the operator with exactly the same operands would produce the same value again.
