cassini: Fix a memory leak in the error handling path of cas_init_one()

[ Upstream commit 412cd77a2c24b191c65ea53025222418db09817c ]

cas_saturn_firmware_init() allocates some memory using vmalloc(). This
memory is freed in the .remove() function but not it the error handling
path of the probe.

Add the missing vfree() to avoid a memory leak, should an error occur.
