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