cputlb: remove tb_lock from tlb_flush functions

The acquisition of tb_lock was added when the async tlb_flush
was introduced in e3b9ca810 ("cputlb: introduce tlb_flush_* async work.")

tb_lock was there to allow us to do memset() on the tb_jmp_cache's.
However, since f3ced3c5928 ("tcg: consistently access cpu->tb_jmp_cache
atomically") all accesses to tb_jmp_cache are atomic, so tb_lock
is not needed here. Get rid of it.
