Subject: riscv/sifive: remove warning in errata

riscv/sifive: remove warning in errata

The alternative patching of sifive vendor extensions also calls the
sifive_errata_patch_func(), but the patch_id of the vendor extension
(ext + RISCV_VENDOR_EXT_ALTERNATIVES_BASE) is always larger than
ERRATA_SIFIVE_NUMBER. Remove this unnecessary warning.
