driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8IL6H CVE: NA
----------------------------------------------------------------------
In function debugfs_debugfs_snapshot_global_reg_v3_hw() it uses debugfs_axi_reg.count (which is the number of axi debugfs registers) to acquire the number of global debugfs registers.
Use debugfs_global_reg.count to acquire the number of global debugfs registers instead.
