There is no need to read the H_BLOCK_REMOVE characteristics when running in Radix mode because this hcall is never called.
Furthermore since the commit 387e220a2e5e ("powerpc/64s: Move hash MMU support code under CONFIG_PPC_64S_HASH_MMU") define pseries_lpar_read_hblkrm_characteristics as un empty function if CONFIG_PPC_64S_HASH_MMU is not set, the #ifdef block can be removed.
