[E1000]: Convert regtest macro's to functions

Browse Source 
Minimal macro to function conversion in e1000_ethtool.c

Adds functions reg_pattern_test and reg_set_and_check
Changes REG_PATTERN_TEST and REG_SET_AND_CHECK macros
to call these functions.

Saves ~2.5KB

Compiled x86, untested (no hardware)
