tcg: Rename tb_jmp_remove() to tb_remove_from_jmp_list()

Browse source 
tb_jmp_remove() was only used to remove the TB from a list of all TBs
jumping to the same TB which is n-th jump destination of the given TB.
Put a comment briefly describing the function behavior and rename it to
better reflect its purpose.
