afs: Clean up compiler warning casting ptr to int
In osi_probe.c, the macro 'check_result' casts a pointer to an int which
on older Linux kernels (e.g. 2.6.18) produces several lines with the C
warning:
... warning: cast from pointer to integer of different size
Change the cast from int to long int.
Linux 2.6.18 doesn't provide intptr_t or uintptr_t, and stdint.h is not
available to kernel modules. But the size of a pointer is the size of a
long (see uintptr_t in linux/types.h - Linux 2.6.24+), so
change the cast from int to long.
Note that the this code by default only gets pulled in for older Linux
kernels (e.g. 2.6.18). For newer kernels, ENABLE_LINUX_SYSCALL_PROBING
is not defined, and so most of osi_probe.c is not built.
