octeontx2-af: Fix a potentially spurious error message

When this error message is displayed, we know that the all the bits in the
bitmap are set.

So, bitmap_weight() will return the number of bits of the bitmap, which is
'table->tot_ids'.

It is unlikely that a bit will be cleared between mutex_unlock() and
dev_err(), but, in order to simplify the code and avoid this possibility,
just take 'table->tot_ids'.
