nfs: check wait_on_bit_lock err in page_group_lock
Return errors from wait_on_bit_lock from nfs_page_group_lock. Add a bool argument @wait to nfs_page_group_lock. If true, loop over wait_on_bit_lock until it returns cleanly. If false, return the error from wait_on_bit_lock. Signed-off-by: Weston Andros Adamson <dros@primarydata.com> Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
