[PATCH] usb: storage: freecom: drop useless assignment in init_freecom()

[Sergey Shtylyov <s.shtylyov@omp.ru>]

In init_freecom(), the results of usb_stor_control_msg() calls are stored
in the local variable and then printed out by usb_stor_dbg() (if enabled),
except for the 1st call, the result of which is completely ignored.  Drop
the useless assignment.

Found by Linux Verification Center (linuxtesting.org) with the Svace static
analysis tool.
