[PATCH -next] riscv: errata: fix ‘riscv_cbom_block_size’ variable undeclared

[Zeng Heng]

arch/riscv/errata/thead/errata.c: In function ‘errata_probe_cmo’:
arch/riscv/errata/thead/errata.c:40:2: error: ‘riscv_cbom_block_size’ undeclared (first use in this function); did you mean ‘riscv_init_cbom_blocksize’?
   40 |  riscv_cbom_block_size = L1_CACHE_BYTES;
      |  ^~~~~~~~~~~~~~~~~~~~~
      |  riscv_init_cbom_blocksize

'riscv_cbom_block_size' variable should be declared
without the limitation whether CONFIG_RISCV_ISA_ZICBOM
is enabled or not.
