staging: isdn: remove assignment in if conditionals
Remove variable assignment in if statements in drivers/staging/isdn/avm/b1.c. Issues reported by checkpatch.pl as: ERROR: do not use assignment in if condition Also refactor code around some if statements to remove comparisons to NULL and unnecessary braces in single statement blocks.
