Christophe JAILLET 71933fb69b bcachefs: Fix use-after-free in bch2_dev_add() 
If __bch2_dev_attach_bdev() fails, bch2_dev_free() is called twice.
Once here and another time in the error handling path.

This leads to several use-after-free.

Remove the redundant call and only rely on the error handling path.

Fixes: 6a44735653d4 ("bcachefs: Improved superblock-related error messages")
