Bug 25516: Fix for "Can't call method unblessed on unblessed reference"

Software error:
    Can't call method "unblessed" on unblessed reference at
../reserve/request.pl line 581.
was caused by recent commit with `wantarray` removal in sub pickup_locations in
‘Item.pm’
and visible on fresher Perls (where experimental feature "autoderef" removed
https://www.effectiveperlprogramming.com/2010/11/use-array-references-with-the-array-operators/
)

To test:
    1) Get a clean dev environment after "reset_all"
    2) Add an empty record for “Default checkout, hold and return policy” on
/cgi-bin/koha/admin/smart-rules.pl.
    3) Open item record, like
/cgi-bin/koha/reserve/request.pl?biblionumber=1&borrowernumber=1
    4) Observe the error (Can't call method "unblessed" on unblessed reference
at ../reserve/request.pl line 581.)
    5) Apply patch.
    6) Repeat steps 2 and 3.
    7) Observe that the error is gone.
