ath11k: fix vht guard interval mapping
Guard interval value which comes from VHT_SIG_A TLV has a mapping
where value 0 corresponds to LGI, 1 and 3 corresponds to SGI.
Value 3 which is SGI(0.4us) in VHT was incorrectly mapped to a GI
of 3.2us(only applicable in HE) resulting in incorrect rx GI stats.
Fixing the mapping.
