[IA64] Handle count==0 in sn2_ptc_proc_write()
The fix applied in e0c6d97c "security hole in sn2_ptc_proc_write" didn't take into account the case where count==0 (which results in a buffer underrun when adding the trailing '\0'). Thanks to Andi Kleen for pointing this out. Signed-off-by:Cliff Wickman <cpw@sgi.com> Signed-off-by:
