util/amdfwtool: Fix warning taking address of packed struct member
GCC9 introduced a new warning [-Waddress-of-packed-member]. This
is giving the following warning when building amdfwtool: warning: taking
address of packed member of ‘struct _bios_directory_entry’ may result in
an unaligned pointer value. Looking at the definition of the struct, it
looks like this is probably true.
Since the function being called doesn't read from the values, zeroing
them out in the beginning of the function, the code just passes pointers
to the temporary variables without initializing them.
BUG=None
TEST=Build & use AMD firmware table.
BRANCH=Zork
