[PR ld/22263][PR ld/24676] RISC-V: Avoid spurious R_RISCV_NONE for TLS
GD/IE.
For TLS GD/IE, add the same condition with the relocate_section in the
allocate_dynrelocs, to make sure we won't reserve redundant spaces
for dynamic relocations since the conservative estimatation.
After applying this patch, ld seems no longer generate the spurious
R_RISCV_NONE for pr22263-1 test, and the test in pr24676.

* elfnn-riscv.c (RISCV_TLS_GD_IE_NEED_DYN_RELOC): New defined.
Set NEED_RELOC to true if TLS GD/IE needs dynamic relocations,
and INDX will be the dynamic index.
(allocate_dynrelocs): Don't reserve extra spaces in the rela.got
if RISCV_TLS_GD_IE_NEED_DYN_RELOC set need_reloc to false. This
condition needs to be same as relocate_section.
(relocate_section): Likewise, use the same condition as
allocate_dynrelocs.
