[PATCH] media: platform: amd: Fix inverted logic typo in isp4if_is_cmdq_rb_full()

[Sultan Alsawaf]

Fixes a regression from "[PATCH v2] media: platform: amd: Big squash of
fixes/cleanup on top of v5 patchset".

When bytes_free is *less than or equal to* the size of a fw command, then
the ringbuf is full. Fix the inverted logic typo that used `>` instead of
`<=` for the comparison.

Resolves low preview frame rate observed in Zoom.
