drm/amdgpu/userq: return the memdup_user() error for the user MQD

Browse source

mes_userq_mqd_create() returns -ENOMEM when copying the user MQD fails,
even though memdup_user() returns -EFAULT for a bad pointer or -EINTR
when interrupted by a signal. Return PTR_ERR() instead.

While at it drop the error messages. Neither case is a driver error and
userspace shouldn't be able to spam the log with invalid IOCTL
parameters.

v2: drop the error messages (Christian)
