Revert "Solve issues with hip-vdi runtime static lib"

This reverts commit 4c2ab3f41e.

Reason for revert: It is causing dkms-no-npi-hipclang broken.
It is top priority to maintain dkms-no-npi-hipclang build, otherwise we lose track of regression analysis.
So revert the change for now and recommit it after fixing it.
