libext2fs: fix potential races in unix_io
When unix_io does not use pread/pread64 (which is the case the bounce
buffer is in use, either when Direct I/O is in use or the
IO_FLAG_FORCE_BOUNCE in enabled), there are races between the llseek
and and read or write system calls. Fix this by using the BOUNCE_MTX
so only one thread is using the file descriptor at a time.
