The two arrays only had space for 4 units, so didn't work for larger
numbers of units. I thought I'd eliminated these before submitting the
original driver patches.
Also fixed error return on ipath_sysfs_unit_write to not set an error
code if the sysfs code reports consuming more chars than we wrote (since
that can include the nul, and the user doesn't have to include the nul
in the write).
Also changed from ipath_set_sps_lid() to ipath_set_lid(); the sps
was a leftover piece of naming.
