net/http: use default HTTP/2 frame scheduler

Browse Source 
Use the default frame scheduler (currently round-robin)
rather than overriding the default with the priority scheduler.

The priority scheduler is slow, known buggy, and implements
a deprecated stream prioritization mechanism. The default
changed in x/net about a year ago, but we missed that net/http
is overriding that default.

Fixes #67706
