After commit 91cc526b15 "MdeModulePkg/SerialDxe: Fix not able to change
serial attributes", serial is initialized using the reset method that
will call SetAttributes.
However, SetAttributes may return EFI_INVALID_PARAMETER when a driver
does not support some parameters. This will be propagated by the reset
function and lead to UEFI failing to get the console setup.
For instance, this is the case when using the Xen console driver.
Fix it by introspecting the result and return EFI_SUCCESS when the
SetAttributes report an invalid parameter (i.e EFI_INVALID_PARAMETER).
