msm: pcie: correct the shadow save for RC L1 register 

When reading shadow registers, the wrong value is being
recovered for root complex L1 register. Currently,
the value being recovered is a shadow of the endpoint's
L1 register. This change will recover the correct shadow
value for RC L1 register.
