Star Zeng 27bf6712b4 IntelSiliconPkg VTdDxe: Report status code for VTd error
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1273

Current code only uses DEBUG() for VTd error.
This patch updates to also report status code for VTd error.

Test done:
Created case that has VTd error and confirmed the error
status code could be reported as expected.

Star Zeng 8653ea2088 IntelSiliconPkg IntelVTdDxe: Fix incorrect code to clear VTd error
According to VTd spec, Software writes the value read from this
field (F) to Clear it. But current code is using 0 to clear the
field, that is incorrect.

And R_FSTS_REG register value clearing should be not in the for loop.

Without this patch, we will see same VTd error message appears again
and again after it occurs first time.
