[PATCH] net: qrtr: fix handling of confirm_rx field

[Alexander Wilhelm]

Convert confirm_rx to little endian when enqueueing by using cpu_to_le32(),
as big endian systems otherwise interpret the value incorrectly.

When receiving, apply le32_to_cpu(). !! ensures the result becomes 0 or 1
in native CPU endianness, so this conversion is not strictly required, but
it is kept for consistency, clarity, and future safety.
