If 'prefix' is not used, pass NULL instead of empty string as the
last parameter of debugfs_print_regs32().

This function is only used (twice) by the author of it, and the
'prefix' feature is never used. But it's a well-documented debugfs
API. It's added one year ago and appeared in many documents. I still
prefer to let this API stay unchanged and treat the empty string as
typo.
