[PATCH] scsi: target: configfs: Remove redundant assignment to ret

[Jiapeng Chong]

Variable ret is set to '-EINVAL' but this value is never read as it is
overwritten later on, hence it is a redundant assignment and can be
removed.

Clean up the following clang-analyzer warning:

drivers/target/target_core_configfs.c:2037:5: warning: Value stored to
'ret' is never read [clang-analyzer-deadcode.DeadStores].

drivers/target/target_core_configfs.c:1973:5: warning: Value stored to
'ret' is never read [clang-analyzer-deadcode.DeadStores].

drivers/target/target_core_configfs.c:1959:5: warning: Value stored to
'ret' is never read [clang-analyzer-deadcode.DeadStores].
