[PATCH] Fix build errors if bitop functions are do {} while macros 

If one of clear_bit, change_bit or set_bit is defined as a do { } while (0)
function usage of these functions in parenthesis like

  (foo_bit(23, &var))

while be expaned to something like

  (do { ... } while (0)}).

resulting in a build error.  This patch removes the useless parenthesis.
