shmem: fix tmpfs to handle the huge= option properly
 
shmem_get_unmapped_area() checks SHMEM_SB(sb)->huge incorrectly, which
leads to a reversed effect of "huge=" mount option.

Fix the check in shmem_get_unmapped_area().

Note, the default value of SHMEM_SB(sb)->huge remains as
SHMEM_HUGE_NEVER.  User will need to specify "huge=" option to enable
huge page mappings.
