wilc1000: fix RCU usage in connect path With lockdep enabled, calls to the
connect function from cfg802.11 layer lead to the following warning:

path, when trying to parse target BSS parameters, we dereference a RCU
pointer whithout being in RCU critical section. Fix RCU dereference usage
by moving it to a RCU read critical section. To avoid wrapping the whole
wilc_parse_join_bss_param under the critical section, just use the critical
section to copy ies data
