ASoC: SOF: sof-client-probes-ipc4: add checks to prevent static analysis warnings
make KCFLAGS='-fanalyzer' sound/soc/sof/ reports several NULL pointer
dereference paths.

sof_ipc4_probe_get_module_info() can return a NULL value, but it's
only tested in the init state. Static analyzers cannot know the probe
state machine and hence flags a potential issue for all calls of that
function.

Squelch these errors by adding the same check consistently.
