bde8adb808eeffb02fdcbd3425f09f1645bdcf4a target/i386: Remove dead assignment to ss in do_interrupt64()
Coverity points out that in do_interrupt64() in the "to inner
privilege" codepath we set "ss = 0", but because we also set
"new_stack = 1" there, later in the function we will always override
that value of ss with "ss = 0 | dpl".
Remove the unnecessary initialization of ss, which allows us to
reduce the scope of the variable to only where it is used. Borrow a
comment from helper_lcall_protected() that explains what "0 | dpl"
means here.
