drm/amdkfd: Fix NULL pointer check order in kfd_ioctl_create_process
In kfd_ioctl_create_process(), the pointer 'p' is used before checking
if it is NULL.
The code accesses p->context_id before validating 'p'. This can lead
to a possible NULL pointer dereference.
Move the NULL check before using 'p' so that the pointer is validated
before access.
Fixes the below:
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_chardev.c:3177 kfd_ioctl_create_process() warn: variable dereferenced before check 'p' (see line 3174)
Fixes: cc6b66d661fd ("amdkfd: introduce new ioctl AMDKFD_IOC_CREATE_PROCESS")
