SPI lock not aquired

## Problem
`adafruit_esp32spi.py` throws the below RuntimeError

```
Traceback (most recent call last):
File "code.py", line 21, in

RuntimeError: Function requires lock
```

## How to reproduce

1. Play a sound file _from an sd card_ (via SPI) with `audioio.AudioOut`
2. Without waiting for it to finish, use `adafruit_requests` (which uses `adafruit_esp32spi/adafruit_esp32spi_socket`)

Inspecting the error, I would guess that `_read_byte` should be acquiring a lock on the SPI bus, which is being used to play audio (with DMA if I had to guess).

## Hardware Config
```
Adafruit CircuitPython 7.3.1 on 2022-06-22; Adafruit PyPortal Titano with samd51j20
Board ID:pyportal_titano
```

Start with adafruit_esp32spi/adafruit_esp32spi.py, especially _read_byte, _check_data, _wait_response_cmd, and _send_command_get_response, then trace the socket_open path shown in the traceback. Reproduce the audio-over-SPI and adafruit_requests interaction on the PyPortal Titano configuration; done means the request no longer raises RuntimeError: Function requires lock.
