afs: fix afs_linux_mmap fstrace entry

Browse Source 
The format string for CM_TRACE_GMAP takes 4 substitutions, but
afs_linux_mmap only supplies 3.  This results in malformed output from
fstrace:

Type mismatch, using raw print.
Gn_map vp 0x%lx addr 0x%lx len 0x%x off 0x%x (afs / zcm)raw op
701087775, time 715.322573, pid 9644
p0:0xc0a66ec0 p1:0x8b81a000 p2:131072

Repair the recording of CM_TRACE_GMAP.
