staging/csr: clean coding style in uf_start_thread

in bh.c the function uf_start_thread needed a coding style fixes.

The following fixes:

* fix no space at the start of line
* fix over 80 character lines
* fix no brace needed for single statement blocks (if..else or for and while)
* use tabs instead of 4 spaces at the start of every line
