Clang static checker(scan-build) warning：
drivers/firmware/arm_scmi/driver.c:line 2915, column 2
Attempt to free released memory.
When devm_add_action_or_reset() failed , scmi_debugfs_common_cleanup()
will run twice which caused double free of 'dbg->name'.
Remove the redundant scmi_debugfs_common_cleanup() to fix this problem.
Fixes: c3d4aed763ce ("firmware: arm_scmi: Populate a common SCMI debugfs root")
