[Intel-wired-lan] [PATCH v2 03/13] ice: Fix missing shift

[Anirudh Venkataramanan]

From: Bruce Allan <bruce.w.allan at intel.com>

The ITR index of the interrupt cause for OICR and FW interrupts is not
being shifted correctly so when masked with PFINT_*_CTL_ITR_INDX_M it
will always be zero.  Luckily, ICE_RX_ITR is zero anyway so the end result
is the same, but the shift should be fixed in case the value of ICE_RX_ITR
ever changes or it is substituted with another value that needs to be
shifted properly.
