This fixes a bug introduced in commit de4ef86cfc
("dccp: fix dccp rmmod when kernel configured to use slub", 17 Jan): the
vsnprintf used sizeof(slab_name_fmt), which became truncated to 4 bytes, since
slab_name_fmt is now a 4-byte pointer and no longer a 32-character array.
This lead to error messages such as
FATAL: Error inserting dccp: No buffer space available
>> kernel: [ 1456.341501] kmem_cache_create: duplicate cache cci
generated due to the truncation after the 3rd character.
Fixed for the moment by introducing a symbolic constant. Tested to fix the bug.
