[PATCH v2] of: property: Fix documentation for out values

[Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com>]

Property fetching functions which return number of successfully fetched
properties should not state that out-values are only modified if 0 is
returned. Fix this. Also, "pointer to return value" is slightly suboptimal
phrase as "return value" commonly refers to value function returns (not via
arguments). Rather use "pointer to found values".

Changes from v1. Removed statement about modifying arg ptr only upon
successful execution (as requested by Frank). Also changed "pointer to
return value" with "pointer to found values"
