Remove Use_Test_Access option

Ganesha really depends on doing all permission checking, we will not
defer permission checking to the underlying file system.

Use fsal_set_credentials in GPFSFSAL_unlink, GPFSFSAL_rename, and GPFSFSAL_link

Due to atomicity problems, GPFS needs to do the permission checking for
directory mutating operations, so set the thread credentials to allow that and
strip the old explicit permission checking.

Remove unused FSAL_OWNER_OK flag

This flag was originally implemented to allow permission checking to evaluate
the conditions where the file owner is allowed access despite the mode or ACL.
This condition is now evaluated directly for I/O operations.

Allow root execute permission if someone is allowed execute

For mode check, test is simple.

For ACL check, if we are looking for execute permission for root,
we walk the ACL, and consider ANY ACE as applicable, however, we
then ignore a DENY ACE.

Use cache_inode_access_no_mutex wrapper instead of calling cache_inode_access_sw

These two external callers of cache_inode_access_sw make the same call as
cache_inode_access_no_mutex, making use of that wrapper will simplify some
later patches.
