Fix FreeBSD sendfile
check (nbytes == 0 && d->c.sendfile.nbytes == 0) when efile_sendfile returns 0 and
has EAGAIN set.
FreeBSD sendfile(2) man page:
When using a socket marked for non-blocking I/O, sendfile() may send
fewer bytes than requested. In this case, the number of bytes
successfully written is returned in *sbytes (if specified), and the error
EAGAIN is returned.
The number of bytes successfully written can be 0. If this happens and
in a request handling either file:sendfile/2 or file:sendfile/5 with Bytes=0,
the sendfile loop will stop prematurely and file:sendfile will return
{ok, BytesSent} where BytesSent < DataAfterOffset, effectively breaking sendfile
support on FreeBSD.
