[PATCH] IB/srp: Fix a 32-bit compiler warning

[Bart Van Assche <bvanassche-HInyCGIudOg@public.gmane.org>]

The result of a pointer subtraction has type ptrdiff_t. Hence change a
%ld format specifier into %td. This change avoids that the following
warning is printed on 32-bit systems:

warning: format '%ld' expects argument of type 'long int', but argument 5 has type 'int' [-Wformat=]
