target/mips: use lookup_and_goto_ptr on BS_STOP

Browse source 
The TB after BS_STOP is not fixed (e.g. helper_mtc0_hwrena
changes hflags, which ends up changing the TB flags via
cpu_get_tb_cpu_state). This requires a full lookup (i.e.
with flags) via lookup_and_goto_ptr instead of gen_goto_tb,
since the latter only looks at the PC for in-page goto's. Fix it.

Backports commit cd314a7d0190a03122ca0606ecf71b4b873a22c6 from qemu.
