ipw2x00: remove redundant variables len, ret, reason and crypt

Browse Source 
Variables len, ret, reason and crypt are assigned values that
are never read, hence they are redundant and can be removed.

Note: For the variable ret, a return code is being assigned, but
this is not returned and 0 is currently being returned, I believe
this is OK.

Cleans up clang warnings:
warning: variable 'len' set but not used [-Wunused-but-set-variable]
variable 'ret' set but not used [-Wunused-but-set-variable]
warning: variable 'reason' set but not used [-Wunused-but-set-variable]
warning: variable 'crypt' set but not used [-Wunused-but-set-variable]
