Description: This patch is aimed to fix the the pointer 'ctx1' uninitialized error with gcc4.5.1 as described below.
Download dpdk source code from http://dpdk.org, and compile the source code(commit cc333208d5658fea642098b665cd429e6cda54a9).
It has the following compilation error on fedora14 with gcc4.5.1 while it is fine on Fedorak20 with gcc4.8.2:
"dpdk/lib/librte_kvargs/rte_kvargs.c:51:14: error: 'ctx1' may be used uninitialized in this function"
According to the latest DPDK OS Building Test Report(commit:cc333208d5658fea642098b665cd429e6cda54a9, the master branch from http://dpdk.org), 
this error also occurs on SUSE11SP2_64 with gcc4.5.1, SUSE11SP3_32 with gcc4.5.1 and SUSE11SP3_64 with gcc4.3.4. 
Initializing the pointer can solve this problem.
