alsa-util: Perform format and rate detection before setting HW params

Igor Kovalenko requested to merge igor.v.kovalenko/pulseaudio:pr/detect-format-and-sample-rate-early into master

Perform detection of supported sample format and rates just after device is opened, before snd_pcm_hw_params() is called for the first time.

This fixes a problem where device restricts available sample rates after HW params are set preventing sample rate detection (seen with UAC2 devices and kernel 6.1.9)

Closes: #1414 (closed)

Bug: https://github.com/alsa-project/alsa-lib/issues/119
