We need to explicitly mark OPPs as shared, when they are not defined
with OPP-v2 bindings. But this isn't required to be done if we failed to
initialize OPP table.

Reorder code to verify OPP count before marking them shared.

Fixes: 2e02d8723edf ("cpufreq: dt: Add support for operating-points-v2 bindings")
