Xiao Wang 19685d5aa7 igb_uio: allow multi-process access 
In some case, one device are accessed by different processes via
different BARs, so one uio device may be opened by more than one
process, for this case we just need to enable interrupt once, and
pci_clear_master only when the last process closed.

Fixes: 5f6ff30dc5 ("igb_uio: fix interrupt enablement after FLR in VM")
