[PATCH v2] Staging: rtl8188eu: Remove redundant if conditions

[Vatika Harlalka <vatikaharlalka@gmail.com>]

Remove redundant if blocks as is2t is always false.
Variable rf is always 1 as is2t is false.
Variable value32 is unused after removing redundant code.

 Changes in v2: Added one new unused if() block.
