igb_uio: remove device reset in open

Browse Source 
Remove device reset during application start, the reset for application
exit still there.

Reset in open removed because of following comments:
1- Device reset not completed when VF driver loaded, which cause VF PMD
   initialization error.
   Adding delay can solve the issue but will increase driver load time.

2- Reset will be issues all devices unconditionally, not very efficient
   way.
