[Intel-wired-lan] [next PATCH S51 7/9] i40e: fix compile error due to type conflict

[Bimmy Pujari]

From: Matt Jared <matthew.a.jared at intel.com>

For the clause 22 and 45 phy register read funcions, cast u32 variables to
u8, resolving compiler error due to data being truncated when placing it
in u8 variable.
