[PATCH] drm/msm/disp: add error value record in for circle`s error index

[Bernard Zhao]

In function dpu_core_irq_enable & dpu_core_irq_disable, when
some index enable or disable failed, return value will be
covered by next success index. Upper call function will not
catch this error, this maybe does not meet the expectation.
This change is to make the code a bit more readable.
