[PATCH] sas transport sysfs write attributes bug fix

[Eric Moore <eric.moore@lsil.com>]

The SAS Transport Layers SySFS write attributes were recently broke when
SETUP_OPTIONAL_PORT_ATTRIBUTE_WRONLY was added.  This fix's the following
write attributes:

	/sys/class/sas_phy/phy-0:0/hard_reset
	/sys/class/sas_phy/phy-0:0/link_reset
