nilfs2: hide function name argument from nilfs_error()
Simplify nilfs_error(), an output function used to report critical
issues in file system. This renames the original nilfs_error() function
to __nilfs_error() and redefines it as a macro to hide its function name
argument within the macro.
Every call site of nilfs_error() is changed to strip __func__ argument
except nilfs_bmap_convert_error(); nilfs_bmap_convert_error() directly
calls __nilfs_error() because it inherits caller's function name.
