Lizhi Hou 03808abb1d accel/amdxdna: Prevent ubuf size overflow 
The ubuf size calculation may overflow, resulting in an undersized
allocation and possible memory corruption.

Use check_add_overflow() helpers to validate the size calculation before
allocation.

Fixes: bd72d4acda ("accel/amdxdna: Support user space allocated buffer")
