gpu: host1x: remove redundant assignment to variable space

The variable space is being initialized with a value that is never read,
it is being re-assigned later on. The initialization is redundant and
can be removed. Also merge two declaration lines together.

Cleans up clang scan build warning:
drivers/gpu/host1x/cdma.c:628:15: warning: Value stored to 'space'
during its initialization is never read [deadcode.DeadStores]
