proc: mounts_poll() make consistent to mdstat_poll
In recently sysfs_poll discussion, Neil Brown pointed out /proc/mounts
also should be fixed.
SUSv3 says "Regular files shall always poll TRUE for reading and
writing". see
http://www.opengroup.org/onlinepubs/009695399/functions/poll.html
Then, mounts_poll()'s default should be "POLLIN | POLLRDNORM". it mean
always readable.
In addition, event trigger should use "POLLERR | POLLPRI" instead
POLLERR. it makes consistent to mdstat_poll() and sysfs_poll(). and,
select(2) can handle POLLPRI easily.
