rtl8xxxu: Remove set but not used variables 'usedesc40' and 'seq_number' 



Fixes gcc '-Wunused-but-set-variable' warning:

drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c: In function 'rtl8xxxu_tx':
drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c:4925:7: warning:
 variable 'usedesc40' set but not used [-Wunused-but-set-variable]

drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c:4921:6: warning:
 variable 'seq_number' set but not used [-Wunused-but-set-variable]

'usedesc40' and 'seq_number' are not used any more after
commit b59415c2 ("rtl8xxxu: Split filling of TX descriptors into separate functions")
