Subject: [PATCH][next] bcachefs: remove redundant initialization of variable level

Variable level is being initialized a value that is never read, the
variable is being re-assigned another value several statements later
on. The initialization is redundant and can be removed. Cleans up
clang scan build warning:

fs/bcachefs/btree_iter.c:1217:11: warning: Value stored to 'level'
during its initialization is never read [deadcode.DeadStores]
