ubik: remove unnecessary lseeks in uphys_open
The ubik database file access layer has a file descriptor cache to avoid
reopening the database file on each file access. However, the file
offset is reset with lseek on each and every use of the cached file
descriptor, and the file offset is set twice when reading or writing
data records.
This change removes unnecessary and duplicate lseek system calls to
reduce the system call load.
