cbfstool: Fix build error with clang when comparing enum
If HOSTCC=clang, the -Wtautological-constant-out-of-range-compare is
set automaticaaly. That assume the value of type enum is in the defined
range. Then testing if a type enum is out of range causes build error.
Error:
coreboot/util/cbfstool/cbfs_image.c:1387:16: error:
comparison of constant 4 with expression of type 'enum vb2_hash_algorithm'
is always false [-Werror,-Wtautological-constant-out-of-range-compare]
if (hash_type >= CBFS_NUM_SUPPORTED_HASHES)
~~~~~~~~~ ^ ~~~~~~~~~~~~~~~~~~~~~~~~~
