[PATCH] drm/amdgpu: Replace deprecated strcpy() in amdgpu_virt_write_vf2pf_data

[Yicong Hui <yiconghui@gmail.com>]

strcpy() is deprecated as it does not do any bounds checking (as
specified in Documentation/process/deprecated.rst).

There is a risk of buffer overflow in the case that the value for
THIS_MODULE->version exceeds the 64 characters. This is unlikely, but
replacing the deprecated function will pre-emptively remove this risk
entirely.

Replace both instances of strcpy() with the safer strscpy() function.

Changes have been compile tested.
