bitmap: replace _reg_op(REG_OP_ISFREE) with find_next_bit()
_reg_op(REG_OP_ISFREE) can be trivially replaced with find_next_bit(). Doing that opens room for potential small_const_nbits() optimization. CC: Andy Shevchenko <andriy.shevchenko@linux.intel.com> CC: Rasmus Villemoes <linux@rasmusvillemoes.dk> Signed-off-by: Yury Norov <yury.norov@gmail.com>
