[PATCH] nfs-utils: FQDNs in the rmtab causes exportfs to seg fault

[Steve Dickson]

When a FQDN exists in /var/lib/nfs/rmtab it causes 
the exportfs command to seg fault due to the nfs_export pointer 
not being allocated. Reworking the parentheses in rmtab_read() 
so the htype variable is evaluated correctly fix the problem.
