can: usb: peak: rename peak_usb dump_mem function

Rename generic-sounding function dump_mem() to pcan_dump_mem()
so that it does not conflict with the dump_mem() function in
arch/sh/include/asm/kdebug.h.

drivers/net/can/usb/peak_usb/pcan_usb_core.c: error: conflicting types for 'dump_mem':  => 56:6
