The RIOT community cares a lot about code quality.
Therefore, before describing what your contribution is about, we would like
you to make sure that your modifications are compliant with the RIOT
coding conventions, see https://github.com/RIOT-OS/RIOT/wiki/Coding-conventions.

### Contribution description

at the file drivers/at.c there's the uart_init function which returns 0 no matter what, in case the function failed the user/tester won't know that it failed or why.
i changed the function uart_init to return the result of the uart_init which could be:

then in tests/driver_at/main in the init function, i checked if the result code is equal to one of the last two, if yes, i printed it and returned 1.

### Testing procedure

Details steps to test your contribution:
-you can compile driver_at test, for any of the at devices
-it was working, just not correctly, in my opinion.
- the expected success test output
in case of wrong uart:
"Invalid UART device given!"
or in case of wrong baudrate:
"Baudrate is not applicable!"
