Count write times when extending relation files for shared buffers
Relation files extended by multiple blocks at a time have been counting
the number of blocks written, but forgot to increment the write time in
this case, as single-block write and relation extension are treated as
two different I/O operations in the shared stats: IOOP_EXTEND vs
IOOP_WRITE. In this case IOOP_EXTEND was forgotten for normal
(non-temporary) relations, still the number of blocks written was
incremented according to the relation extend done.
Write times are tracked when track_io_timing is enabled, which is not
the case by default.
