[PATCH] infiniband/hw/ocrdma: increase frame warning limit in verifier when using KASAN or KCSAN

[flyingpenghao@gmail.com]

From: Peng Hao <flyingpeng@tencent.com>

When building kernel with clang, which will typically
have sanitizers enabled, there is a warning about a large stack frame.

drivers/infiniband/hw/ocrdma/ocrdma_stats.c:686:16: error: stack frame size (20664) exceeds limit (8192) in 'ocrdma_dbgfs_ops_read' [-Werror,-Wframe-larger-than]
static ssize_t ocrdma_dbgfs_ops_read(struct file *filp, char __user *buffer,
               ^

Increase the frame size by 20% to set.
