[PATCH] ISDN: several minor fixes

[PATCH] ISDN: several minor fixes

pcbit: kill 'may be used uninitialized' warning.  although the code does
eventually fill the 32 bits it cares about, the variable truly is
accessed uninitialized in each macro.  Easier to just clean it up now.

sc: fix a ton of obviously incorrect printk's (some with missing
arguments even)
