ext4: save all error info in save_error_info() and drop ext4_set_errno()
Using a separate function, ext4_set_errno() to set the errno is problematic because it doesn't do the right thing once s_last_error_errorcode is non-zero. It's also less racy to set all of the error information all at once. (Also, as a bonus, it shrinks code size slightly.)
