[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.
