preadv/pwritev: fix offset argument type
preadv/pwritev don't provide separate version for 64-bit wide off_t, and default to 32-bit wide off_t, which results in a mismatch between declaration and definition for user programs built with -D_FILE_OFFSET_BITS=64. Make offset argument of both functions __off64_t. This fixes test misc/tst-preadvwritev on xtensa. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
