hfsplus: don't set REQ_SYNC for hfsplus_submit_bio()

hfsplus_submit_bio() called by hfsplus_sync_fs() uses bdev_virt_rw() which
in turn uses submit_bio_wait() to submit the BIO.

But submit_bio_wait() already sets the REQ_SYNC flag on the BIO so there
is no need for setting the flag in hfsplus_sync_fs() when calling
hfsplus_submit_bio().
