[PATCH 26/27] attr: push the bare repo check into read_attr()

[Brandon Williams]

Push the bare repository check into the 'read_attr()' function.  This
avoids needing to have extra logic which creates an empty stack frame
when inside a bare repo as a similar bit of logic already exists in the
'read_attr()' function.
