RDMA/ocrdma: Fix permissions for OCRDMA_RESET_STATS

Browse Source 
[ Upstream commit 744820869166c8c78be891240cf5f66e8a333694 ]

Debugfs file reset_stats is created with S_IRUSR permissions,
but ocrdma_dbgfs_ops_read() doesn't support OCRDMA_RESET_STATS,
whereas ocrdma_dbgfs_ops_write() supports only OCRDMA_RESET_STATS.

The patch fixes misstype with permissions.
