Subject: [net-next 07/11] igb: Drop unnecessary write of E1000_IMS from igb_msix_other

From: Alexander Duyck <alexander.h.duyck@...el.com>

Since we mask interrupts in EIMS not in IMS there is no need to re-enable
mask bits in that register.  As such we can remove the write to IMS from
the end of igb_msix_other.
