ipmi:ssif: Ignore spaces when comparing I2C adapter names

Some of the adapters have spaces in their names, but that's really
hard to pass in as a module or kernel parameters.  So ignore the
spaces.

The addresses are normal I2C addresses. The adapter is the string
name of the adapter, as shown in /sys/class/i2c-adapter/i2c-<n>/name.
It is *NOT* i2c-<n> itself.
It is *NOT* i2c-<n> itself. Also, the comparison is done ignoring
spaces, so if the name is "This is an I2C chip" you can say
adapter_name=ThisisanI2cchip. This is because it's hard to pass in
spaces in kernel parameters.
