[PATCH 15/16] xtensa: umulsidi3: fix conditional expression

[Randy Dunlap]

Even when a variant has one or more of these defines set to 1, the
multiplier code paths are not used. Change the expression so that the
correct code paths are used.

arch/xtensa/lib/umulsidi3.S:44:38: warning: "XCHAL_NO_MUL" is not defined, evaluates to 0 [-Wundef]
   44 | #if defined(__XTENSA_CALL0_ABI__) && XCHAL_NO_MUL
arch/xtensa/lib/umulsidi3.S:145:38: warning: "XCHAL_NO_MUL" is not defined, evaluates to 0 [-Wundef]
  145 | #if defined(__XTENSA_CALL0_ABI__) && XCHAL_NO_MUL
arch/xtensa/lib/umulsidi3.S:159:5: warning: "XCHAL_NO_MUL" is not defined, evaluates to 0 [-Wundef]
  159 | #if XCHAL_NO_MUL
