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
