Change the 'ret' variable in __bch2_dev_attach_bdev() from unsigned to int, as it needs to store either negative error codes or zero.
Storing the negative error codes in unsigned type, doesn't cause an issue at runtime but can be confusing. Additionally, assigning negative error codes to unsigned type may trigger a GCC warning when the -Wsign-conversion flag is enabled. No effect on runtime.
