EDAC/ie31200: #undef field_get() before local definition

Browse Source 
Prepare for the advent of a globally available common field_get() macro
by undefining the symbol before defining a local variant.  This prevents
redefinition warnings from the C preprocessor when introducing the common
macro later.
