disp: msm: dsi: Nullify display modes after kfree

Browse source 
The 'display->modes' pointer must be set to NULL immediately
after calling kfree on it to prevent potential double-free
vulnerabilities or use-after-free issues.

This change ensures robust memory management by clearing the
pointer to previously freed memory, aligning with best practices
for kernel memory deallocation.
