[PATCH] remoteproc/mediatek: fix null pointer dereference on null scp pointer

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

Currently when pointer scp is null a dev_err is being called that
references the pointer which is the very thing we are trying to
avoid doing. Remove the extraneous error message to avoid this
issue.

Addresses-Coverity: ("Dereference after null check")
Fixes: 63c13d61eafe ("remoteproc/mediatek: add SCP support for mt8183")
