libmultipath: stop PURE FlashArray from detecting priority

If 'detect_prio' is set to 'yes', the 'sysfs' prioritizer will be used instead of the 'alua' prioritizer. The 'sysfs' prioritizer can leave paths in the Active/Non-optimized ALUA state after a successful upgrade of a PURE FlashArray. Explicitly use the 'alua' prioritizer instead for PURE FlashArray rather than the default of 'detect_prio' which is 'yes'.
