lib: crc32: mark static variable as __efi_runtime_data
In commit 483dbab9f931 ("lib: crc32: mark function crc32() as
__efi_runtime") one local static variable was missed. It did not end up in
the __efi_runtime_data section as it should.
If CONFIG_DYNAMIC_CRC_TABLE=y a data abort execption may occur when the
UEFI payload calls the SetVirtualAddressMap() runtime service.
