conn: prevent duplicate flag conversion in high-level interface
The high-level interface triggers flag conversion twice: once in the
high-level init and once in the low-level init. This caused false
"both 'want' and 'want_ext' are set" errors when using
fuse_set_feature_flag() or fuse_unset_feature_flag().
The existing check for duplicate conversion only worked when 32-bit
flags were set directly. When using the preferred flag manipulation
functions, conn->want and the lower 32 bits of conn->want_ext
would differ, triggering the error.
Fix this by synchronizing conn->want with the lower 32 bits of
conn->want_ext after conversion, ensuring consistent state for
subsequent calls.
