wil6210: debugfs: Fix a couple of formatting issues in 'wil6210_debugfs_init'

Kerneldoc expects attributes/parameters to be in '@*.: ' format and
gets confused if the variable does not follow the type/attribute
definitions.

Fixes the following W=1 kernel build warning(s):

 drivers/net/wireless/ath/wil6210/debugfs.c:456: warning: Function parameter or member 'wil' not described in 'wil6210_debugfs_init_offset'
 drivers/net/wireless/ath/wil6210/debugfs.c:456: warning: Function parameter or member 'dbg' not described in 'wil6210_debugfs_init_offset'
 drivers/net/wireless/ath/wil6210/debugfs.c:456: warning: Function parameter or member 'base' not described in 'wil6210_debugfs_init_offset'
 drivers/net/wireless/ath/wil6210/debugfs.c:456: warning: Function parameter or member 'tbl' not described in 'wil6210_debugfs_init_offset'
