[PATCH] drm/amd/display: Delete a redundant memory setting in amdgpu_dm_irq_register_interrupt()

[Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>

The memory was set to zero already by a call of the function “kzalloc”.
Thus remove an extra call of the function “memset” for this purpose.

This issue was detected by using the Coccinelle software.
