e85e36390c e1000e: rename e1000e_reload_nvm() and call as function pointer
Rename e1000e_reload_nvm() to e1000e_reload_nvm_generic() to signify the
function is used for more than one MAC-family type, and set and use it as a
MAC ops function pointer to be consistent with the driver design.

Rename e1000e_setup_link() to e1000e_setup_link_generic() to signify the

5015e53a4c e1000e: cleanup goto statements to exit points without common work
Per ./Documentation/CodingStyle, goto statements are acceptable for the
centralized exiting of functions when there are multiple exit points which
share common work such as cleanup.  When no common work is required for
multiple exit points, the function should just return at these exit points
instead of doing an unnecessary jump to a centralized return.  This patch
cleans up the inappropriate use of goto statements, and removes unnecessary
variables (or move to a smaller scope) where possible as a result of the
cleanups.
