Warning in logging.c

[Vijay Bellur <vbellur@xxxxxxxxxx>]

Hi Bala,

After the syslog improvements got merged, the following warning is being 
seen:

../../../libglusterfs/src/logging.c: In function 'gf_syslog':
../../../libglusterfs/src/logging.c:281:21: warning: variable 'p' set 
but not used [-Wunused-but-set-variable]

Can you please address this?

Thanks,
Vijay
