drm/amdgpu: Fix JPEG v4.0.3 register write

Browse source

[ Upstream commit 8c50bf9beb ]

EXTERNAL_REG_INTERNAL_OFFSET/EXTERNAL_REG_WRITE_ADDR should be used in
pairs. If an external register shouldn't be written, both packets
shouldn't be sent.

Fixes: a78b481469 ("drm/amdgpu: Skip PCTL0_MMHUB_DEEPSLEEP_IB write in jpegv4.0.3 under SRIOV")
