Subject: [PATCH] sched/deadline: Fix lint warnings and errors in deadline.c

- Remove unnecessary 'else' statement following a 'return'
- Correct code indentation to use tabs instead of spaces

This change addresses the following checkpatch warnings and errors:
- WARNING: else is not generally useful after a break or return
- ERROR: code indent should use tabs where possible
- WARNING: please, no spaces at the start of a line
