Bug 762782 (GLUSTER-1050)

Test Plan:
1. Call a fcntl lock as following:
   sample flock structure:
   flock.l_type = F_WRLCK;
   flock.l_start = 0;
   flock.l_len   = 0; //whole file
   flock.l_whence = SEEK_START;
   
   fcntl (fd, F_SETLK, &flock);

2. While the above lock is taken (not unlocked) and fd not closed issue another fcntl call as a F_GETLK as following:
   flock.l_type = F_RDLCK;
   flock.l_start = 0;
   flock.l_len = 0; //whole file
   flock.l_whence = SEEK_START;

   fcntl (fd, F_GETLK, &flock);

This call should result in the flock structure changing to a type of F_UNLCK and the pid of the conflicting lock (pid of the process used in step 1) along with the other structures getting filled appropriately.

The bug is hit, where the l_type returned changes when the server is non-linux (Solaris). Verify on a Solaris server setup that the conflicting lock's flock is exactly the same.
