staging: rtl8192u: Remove an unnecessary NULL check
Clang warns:
drivers/staging/rtl8192u/ieee80211/ieee80211_softmac.c:2663:47: warning:
address of array 'param->u.wpa_ie.data' will always evaluate to 'true'
[-Wpointer-bool-conversion]
(param->u.wpa_ie.len && !param->u.wpa_ie.data))
~~~~~~~~~~~~~~~~~^~~~
This was exposed by commit deabe03523a7 ("Staging: rtl8192u: ieee80211:
Use !x in place of NULL comparisons") because we disable the warning
that would have pointed out the comparison against NULL is also false:
drivers/staging/rtl8192u/ieee80211/ieee80211_softmac.c:2663:46: warning:
comparison of array 'param->u.wpa_ie.data' equal to a null pointer is
always false [-Wtautological-pointer-compare]
(param->u.wpa_ie.len && param->u.wpa_ie.data == NULL))
~~~~~~~~~~~~~~~~^~~~ ~~~~
Remove it so clang no longer warns.
