staging: rtl8192e: Fix smatch warnings regarding large arrays on stack

Smatch reports the follwing warnings:

  CHECK   drivers/staging/rtl8192e/rtllib_rx.c
drivers/staging/rtl8192e/rtllib_rx.c +552 RxReorderIndicatePacket(6) warn: 'prxbIndicateArray' puts 1024 bytes on stack

  CHECK   drivers/staging/rtl8192e/rtl819x_TSProc.c
drivers/staging/rtl8192e/rtl819x_TSProc.c +40 RxPktPendingTimeout(9) warn: 'stats_IndicateArray' puts 1024 bytes on stack

  CHECK   drivers/staging/rtl8192e/r8192E_phy.c
drivers/staging/rtl8192e/r8192E_phy.c +859 rtl8192_phy_SwChnlStepByStep(11) warn: function puts 797 bytes on stack

  CHECK   drivers/staging/rtl8192e/rtllib_rx.c
drivers/staging/rtl8192e/rtllib_rx.c +552 RxReorderIndicatePacket(6) warn: 'prxbIndicateArray' puts 1024 bytes on stack

These are fixed by adding the arrays in question as a union in a struct used
by nearly all routines.
