[PATCH] zonefs: fix build warning for s390 in tracepoints

[PATCH] zonefs: fix build warning for s390 in tracepoints

[Johannes Thumshirn]

s390 (and alpha) define __kernel_ino_t and thus ino_t as unsigned int
instead of unsigned long like the other architectures do.

Zonefs' tracepoints use the %lu format specifier for unsigned long
generating a build warning. So cast inode numbers to (unsigned long) when
printing to get rid of the build warning, like other filesystems do as well.

Fixes: 6716b125b339 ("zonefs: add tracepoints for file operations")
