cxl/decoder: Drop pointless locking
cxl_dpa_rwsem coordinates changes to dpa allocation settings for a given
decoder. cxl_decoder_reset() has no need for a consistent snapshot of the
dpa settings since it is merely clearing out whatever was there previously.
Otherwise, cxl_region_rwsem protects against 'reset' racing 'setup'.
In preparation for converting to rw_semaphore_acquire semantics, drop this
locking.
