mm/shmem: annotate benign data-race in shmem_getattr()
shmem_getattr() reads info->alloced, info->swapped and i_mapping->nrpages
without info->lock to decide whether shmem_recalc_inode() should be
called. shmem_recalc_inode() recomputes these under info->lock, so a
stale read here only affects whether shmem_recalc_inode() runs.
Annotate data_race() to silence KCSAN.
