b44: Fix frequent link changes
 
This fixes the issue of frequent link changes under heavy traffic reported
below:

http://bugzilla.kernel.org/show_bug.cgi?id=7696
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=216338

The b44 chip occasionally needs to be reset when ISTAT_ERRORS are
encountered.  The reset sequence includes a PHY reset that will take many
seconds to complete and cause the link to go down and up.  By skipping the
PHY reset, it will greatly reduce the interruption when ISTAT_ERRORS are
encountered.

Change the full_reset parameter to reset_kind parameter in b44_init_hw().
This will allow PHY reset to be skipped when ISTAT_ERRORS are encountered.
