Allocate correct size buffer

[Sindhu-Devale]

In ctx_alloc_credit function in perftest_resources.c file, ctrl_buf is allocated a size of user_param->num_of_qps however it is being memset to a size of buf_size:

ALLOCATE(ctx->ctrl_buf,uint32_t,user_param->num_of_qps);
memset(&ctx->ctrl_buf[0],0,buf_size);

Fix this by allocating the right size ctrl_buf:

ALLOCATE(ctx->ctrl_buf,uint32_t,buf_size);
