lib/cmdline: Fix an invalid format specifier in an assertion msg
[ Upstream commit d2733a026fc7247ba42d7a8e1b737cf14bf1df21 ]
The correct format specifier for p - n (both p and n are pointers) is
%td, as the type should be ptrdiff_t.
This was discovered by annotating KUnit assertion macros with gcc's
printf specifier, but note that gcc incorrectly suggested a %d or %ld
specifier (depending on the pointer size of the architecture being
built).
Fixes: 0ea09083116d ("lib/cmdline: Allow get_options() to take 0 to validate the input")
