[PATCH v5 next 02/17] selftests/nolibc: Rename w to written in expect_vfprintf()

[david.laight.linux@gmail.com]

From: David Laight <david.laight.linux@gmail.com>

Single character variable names don't make code easy to read.
Rename 'w' (used for the return value from snprintf()) 'written'.

Acked-by: Willy Tarreau <w@1wt.eu>
Signed-off-by: David Laight <david.laight.linux@gmail.com>

Unchanged for v5.
V4: Split out from patch 4.
