hal: set USB RX mixer controls' name before initializing their values

When AHAL restarts, bitwidth, sample rate and channel values are not
initialized properly due to missing of mixer control names.
That results into backend value mismatch between AHAL and driver.

Fix this by setting these mixer controls' name before initializing
their values.
