lib/reed_solomon: Fix array subscript 0 is outside array bounds
The grub_absolute_pointer() is a compound expression that can only work
within a function. We are out of luck here when the pointer variables
require global definition due to ATTRIBUTE_TEXT that have to use fully
initialized global definition because of the way linkers work.
static gf_single_t * const gf_powx ATTRIBUTE_TEXT = (void *) 0x100000;
For the reason given above, use GCC diagnostic pragmas to suppress the
array-bounds warning.
