[PATCH] staging: rt8192u: fix sparse warnings in r8192U_core.c

[Fred <fred.chou.nd@gmail.com>]

Fixed the following warnings in sparse:
drivers/staging/rtl8192u/r8192U_core.c:670:6: warning:
 	symbol 'dump_eprom' was not declared.
	Should it be static?
drivers/staging/rtl8192u/r8192U_core.c:1489:5: warning:
 	symbol 'ComputeTxTime' was not declared.
	Should it be static?
drivers/staging/rtl8192u/r8192U_core.c:1556:14: warning:
	symbol 'txqueue2outpipe' was not declared.
	Should it be static?
drivers/staging/rtl8192u/r8192U_core.c:4876:5: warning:
	symbol 'GetRxPacketShiftBytes819xUsb' was not declared.
	Should it be static?
