xfs: Remove redundant assignment to busy

Source kernel commit: 9673261c32dc2f30863b803374b726a72d16b07c

Variable busy is set to false, but this value is never read as it is
overwritten or not used later on, hence it is a redundant assignment
and can be removed.

Clean up the following clang-analyzer warning:

fs/xfs/libxfs/xfs_alloc.c:1679:2: warning: Value stored to 'busy' is
never read [clang-analyzer-deadcode.DeadStores].
