Alexey Dobriyan e3aded3cc2 isdn/sc: compile breakage re check_reset()
There is check_reset() -- global function in drivers/isdn/sc/
There is check_reset -- variable holding module param in aacraid driver.

On allyesconfig they clash with:

  LD      drivers/built-in.o
drivers/isdn/built-in.o: In function `check_reset':
: multiple definition of `check_reset'
drivers/scsi/built-in.o:(.data+0xe458): first defined here
ld: Warning: size of symbol `check_reset' changed from 4 in drivers/scsi/built-in.o to 219 in drivers/isdn/built-in.o
ld: Warning: type of symbol `check_reset' changed from 1 to 2 in drivers/isdn/built-in.o

Rename the former.
