[Qemu-devel] [PATCH] fix qemu_get_cpu(), should return NULL if CPU not found

[Igor Mammedov]

commit 55e5c2850 breaks CPU not found return value, and returns
CPU corresponding to the last non NULL env.
Fix it by returning CPU only if env is not NULL, otherwise CPU is
not found and function should return NULL.
