rdbmp.c: Fix innocuous UBSan error

A fuzzing test case with an image width of 838860946 triggered a UBSan
error:

rdbmp.c:633:34: runtime error: signed integer overflow:
838860946 * 3 cannot be represented in type 'int'

Because the result is cast to an unsigned int (JDIMENSION), this error
is irrelevant, because

(unsigned int)((int)838860946 * (int)3) ==
(unsigned int)838860946 * (unsigned int)3
