Antonio Quartulli 8106d82b4e fast_transition: fix crash by parsing RSN IE only if present 
When performing a fast transition to another OPEN network the RSN
element won't be there and therefore the bss->rsne is gonna be NULL.

Fix crash by not accessing the rsne member when performing a fast
transition to an AP that doe snot advertise any RSN IE.

Crash caught with gdb:

 src/station.c:station_transition_start() 186, target 34:8f:27:2f:b8:fc

 Program received signal SIGSEGV, Segmentation fault.
