[PATCH 1/2] pstore: move slash handling into common function

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

Both open and stat receive a file path and manually skip over the slash
before calling pstore_get_by_name. Follow-up commit adds one more user
of pstore_get_by_name, so instead of duplicating the flash skip a third
time, move it into pstore_get_by_name.
