[PULL for-5.2 1/2] tcg: Remove assert from set_jmp_reset_offset

[Richard Henderson]

Since 6e6c4efed99, there has been a more appropriate range check
done later at the end of tcg_gen_code.  There, a failing range
check results in a returned error code, which causes the TB to
be restarted at half the size.
