Segmentation fault occurs during truncate

Problem:
Segmentation fault occurs when bricks are nearly full 100% and in
parallel truncate of a file is attempted (No space left on device).
Prerequicite is that performance xlators are activated
(read-ahead, write-behind etc)
while stack unwind of the frames following an error responce
from brick (No space left on device) frame->local includes a memory
location that is not allocated via mem_get but via calloc.
The destroyed frame is always ra_truncate_cbk winded from ra_ftruncate
and the inode ptr is copied to the frame local in the wb_ftruncate.

Fix:
extra check is added for the pool ptr
