RISC-V: Remove m_num_vector_iterations[NFC]

Browse Source 
Notice the m_num_vector_iterations is not used, remove the redundant codes.

Committed.

gcc/ChangeLog:

	* config/riscv/riscv-vector-costs.cc (costs::analyze_loop_vinfo):
	Remove m_num_vector_iterations.
	* config/riscv/riscv-vector-costs.h: Ditto.
