Subject: drivers/rapidio/devices/tsi721.c: make module parameter variable name unique

kbuild test robot reported a non-static variable name collision between a
staging driver and a RapidIO driver, with a generic variable name of
'dbg_level'.

Both drivers should be changed so that they don't use this generic public
variable name.  This patch fixes the RapidIO driver but does not change
the user interface (name) for the module parameter.

drivers/staging/built-in.o:(.bss+0x109d0): multiple definition of `dbg_level'
drivers/rapidio/built-in.o:(.bss+0x16c): first defined here
