Fix maybe_hot_frequency_p

[Jan Hubicka]

Hi,
while converting maybe_hot_frequency_p to profile_counts I did not notice that
it has its own function argument.  This patch prevents ICE with
-fdump-tree-ipa-all-details-blocks.

Comitted as obvious.

        * predict.c (maybe_hot_frequency_p): Do not use cfun.
