Changing code to have better error logging

This changes the error logs to show the file and line number instead of
naming a specific a function where the error originated. In some cases
the function name is kept where it made sense for readibility of the
logs.

Test: Run and tested using `atest keystore2_test` for Rust test and CTS test with `atest CtsKeystoreTestCases`
