kernel-doc: Fix stripping of #define in enums

Browse source 
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'
