ShellPkg: Fix SMBIOS Type 26 probe decoding

Browse source 
Decode the Type 26 Voltage Probe Location and Status fields according
to the SMBIOS 3.9.0 specification, section 7.27, "Voltage Probe
(Type 26)".

Table 95, "Voltage Probe: Location and Status fields", defines bits
4:0 as the Location field and bits 7:5 as the Status field. smbiosview
was decoding these fields in the opposite order, causing the displayed
voltage probe location and status to be swapped.
