Subject: drm/amd/display: clean up a condition in dmub_psr_copy_settings()
Git-commit: a5437e0b81a4cb65e17c5eceec75cf6b28302682
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

We can remove the NULL check for "res_ctx" and
"res_ctx->pipe_ctx[i].stream->link".  Also it's nicer to align the
conditions using spaces so I re-indented a bit.

Longer explanation: The "res_ctx" pointer points to an address in the
middle of a struct so it can't be NULL.  For
"res_ctx->pipe_ctx[i].stream->link" we know that it is equal to "link"
and "link" is non-NULL.
