Johan Hedberg cc2d5f8a45 Bluetooth: drivers: h4: Fix uart_fifo_read return value handling
Make sure negative error returns from uart_fifo_read() are correctly
handled.

In the same go, the logic of reading packet headers (ACL/event/ISO) is
refactored into its own helper function. This also fixes having an
appropriate name for the variable that tracks how many header bytes have
already been read (it was called "to_read" and now it's called
"bytes_read").

Fixes #39805

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM Cortex-M,
Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V, and a large number of
`supported boards`_.
