kernel-doc: Fix stripping of #define in enums
The regex to strip single line #define's in enumerations depends on the
fact that the defines are still stored on separate lines. But the
surrounding code already removed newlines and replaced them with
semicolons.
For example a simple input like
/**
* enum flags - test flags
* @flag1: first flag
* @flag2: second flag
* @flag3: third flag
* @flag4: fourth flag
*/
enum flags {
flag1 = BIT(0),
flag2 = BIT(1),
#define flags_small (flag1 | flag2)
flag3 = BIT(2),
flag4 = BIT(3),
#define flags_big (flag2 | flag3)
};
resulted in parsing warnings like
warning: Enum value '#define flags_small (flag1 | flag2);flag3 = BIT(2)' not described in enum 'flags'
warning: Enum value '#define flags_big (flag2 | flag3);' not described in enum 'flags'
