Renjith Thomas fb6b8dfdec bluetooth: fix distorted audio during Bluetooth SCO HFP/HSP playback 
Issue: When HFP/HSP profile is used with certain BT chipsets, the
audio sounds heavily distorted, with very slow playback full of noise.
During recording, the samples are dropped and it distorts the recorded
audio samples.

The root cause of both the issues are related to the fixed MTU sizes
in the PA stack, which is 48 bytes. Here, the BT chipset CC256x had
180 bytes MTU and it was being under-utilized and the rate at which
the samples were being accepted where not matching the expected rate,
and hence the distortion.

Solution: The appropriate solution to this problem is by reading the
MTU size of the SCO socket using getsockopts dynamically.
