RISC-V: Adjust riscv_can_inline_p

We don't hold any extenison flags in `target_flags`, so no need to
gather the extenison flags in `target_flags`.

gcc/ChangeLog:

	* common/config/riscv/riscv-common.cc (riscv_can_inline_p): Drop
	extension flags check from `target_flags`.
	* config/riscv/riscv-subset.h (riscv_x_target_flags_isa_mask):
	Remove.
	* config/riscv/riscv.cc (riscv_x_target_flags_isa_mask): Remove.
