cxl: Fix lockdep warning while creating afu_err_buff attribute
Presently a lockdep warning is reported during creation of afu_err_buff bin_attribute for the afu. This is caused due to the variable attr.key not pointing to a static class key, hence the function lockdep_init_map reports this warning: BUG: key <some-address> not in .data! The patch fixes this issue by calling sysfs_attr_init on the attr_eb.attr structure before populating it with the afu_err_buff file details. This will populate the attr.key variable with a static class key so that lockdep_init_map stops complaining about the lockdep key not being static.
