iwlwifi: mvm: simplify iwl_mvm_dbgfs_register 

No need to pass the dbgfs_dir just to assign it to mvm.
Assign to mvm and then call iwl_mvm_dbgfs_register.

This is a preparation towards the addition of a delayed
op_mode_start flow.
This will allow to split the op_mode_start flow.
Registration to debugfs must happen after we register to
mac80211 and the registration to mac80211 will soon be
delayed in certain cases. In order not to have to remember
the debugfs_dir in a separate variable, just set it into
the mvm structure so that it can be usable later.

Declare mvm->debugfs_dir in the iwl_mvm structure even when
IWLWIFI_DEBUGFS isn't enabled to simplify the source code.
