drm/msm: return -EBUSY if bo still active When we CPU_PREP a bo with NOSYNC flag (for example, to implement PIPE_TRANSFER_DISCARD_WHOLE_RESOURCE), an -EBUSY return indicates to userspace that the bo is still busy. Previously it was incorrectly returning 0 in this case. And while we're in there throw in an bit of extra sanity checking in case userspace tries to wait for a bogus fence.
