[PATCH v2 3/8] riscv: remove unreachable invalid range check in create_linear_mapping_page_table()

[Sang-Heon Jeon]

create_linear_mapping_page_table() iterates memblock regions with
for_each_mem_range() and breaks the loop when start >= end.
for_each_mem_range() never returns an invalid range, so start < end always.

Therefore the start >= end check is unreachable, so remove it.

No functional change.
