dmaengine: idxd: Replace memset(0) + strscpy() with strscpy_pad()
Replace memset(0) followed by strscpy() with strscpy_pad() to improve
idxd_load_iaa_device_defaults(). This avoids zeroing the memory before
copying the strings and ensures the destination buffers are only written
to once, simplifying the code and improving efficiency.
