libxl: format fd flags with 0x since they are hex.

Commit 93f5194e7270 "libxl: clear O_NONBLOCK|O_NDELAY on migration fd
and reinstate afterwards" added some logging of fcntl.F_GETFL at all
as %x without a 0x prefix to make it clear they numbers are hex. Fix
this alongwith an inadvertent logging of the fd itself as hex.
