Subject: [PATCH 1/4] isdn/eicon: remove unused argument in DBG_ERR call

diva_um_idi_read() can call DBG_ERR with 3 format arguments but using a
format string which only uses 2 of them. Remove the last one.

This bug has been found by adding a __printf attribute to
myDbgPrint_...() functions. As this addition leads the compiler to
report a lot of -Wformat warnings (for example the compiler complains
when "%08x" is used to format a pointer, as it is done with all usages
of "E(%08x)" in um_idi.c), this patch does not add any __printf
attribute.

This patch has only been compile-tested.
