Bluetooth: btnxpuart: Fix glitches seen in dual A2DP streaming
[ Upstream commit 7de119bb79a63f6a1959b83117a98734914fb0b0 ]
This fixes a regression caused by previous commit for fixing truncated
ACL data, which is causing some intermittent glitches when running two
A2DP streams.
serdev_device_write_buf() is the root cause of the glitch, which is
reverted, and the TX work will continue to write until the queue is empty.
This change fixes both issues. No A2DP streaming glitches or truncated
ACL data issue observed.
Fixes: 8023dd220425 ("Bluetooth: btnxpuart: Fix driver sending truncated data")
Fixes: 689ca16e5232 ("Bluetooth: NXP: Add protocol support for NXP Bluetooth chipsets")
