qcacld-3.0: Fix min IE length for FILS indication IE

FILS indication IE minimum length should be 4 bytes (2 bytes for tag and
length) + (2 bytes for realm hash). However current mininum is set to
5 bytes.
Usually AP sends cache identifier also in the FILS indication IE, which
is optional and causes the ie length to be greater than min of 5.
If the AP does not send Cache Identifier and sends only realm hash,
the IE length would be 4, which causes the IE to be skipped in parsing
thereby failing FILS connection.

Fix min IE length to 4 bytes in the frame parser for FILS Indication IE
