mm/hmm.c: remove set but not used variable 'devmem'

Fixes gcc '-Wunused-but-set-variable' warning:

mm/hmm.c: In function 'hmm_devmem_ref_kill':
mm/hmm.c:995:21: warning:
 variable 'devmem' set but not used [-Wunused-but-set-variable]

It not used any more since 35d39f953d4e ("mm, hmm: replace
hmm_devmem_pages_create() with devm_memremap_pages()")
