Subject: [PATCH] block/m68k: z2ram - correct printing of sector_t

If CONFIG_LBDAF=y, `sector_t' becomes `u64' instead of `unsigned long':

drivers/block/z2ram.c: In function ‘do_z2_request’:
drivers/block/z2ram.c:83: warning: format ‘%lu’ expects type ‘long unsigned int’, but argument 2 has type ‘sector_t’

Hence always cast it to `unsigned long long' for printing.
Also do the pr_err() dance, while we're at it.

when I'm talking to journalists I just say "programmer" or something like that.
