bonding: Fix updating of speed/duplex changes
This patch corrects an omission from the following commit:
commit f0c76d61779b153dbfb955db3f144c62d02173c2
Author: Jay Vosburgh <fubar@us.ibm.com>

bonding: refactor mii monitor
The un-refactored code checked the link speed and duplex of
every slave on every pass; the refactored code did not do so.
The 802.3ad and balance-alb/tlb modes utilize the speed and
duplex information, and require it to be kept up to date. This patch
adds a notifier check to perform the appropriate updating when the slave
device speed changes.
