[LTP] [PATCH 0/2] Improve ioprio tests

The ioprio syscall tests rely on ltp internal definitions of the
IOPRIO_XXX() macro defining priority classes and levels. With changes
to the ioprio API to support command duration limits, these internal
definitions are incomplete, causing test case ioprio_set03 to fail.

Avoid this issue by having the iprio tests use the kernel header file
definitions if that header exists. This enables additional checks in
the header file [1] which restores the expected results with test
ioprio_set03.

Note: a review of this patch on the kernel block mailing list would be
very appreciated.

ioprio: use ioprio.h kernel header if it exists
ioprio: Use IOPRIO_PRIO_NUM to check prio range
