Kirill A. Shutemov 5049632bc9 x86/boot/compressed/64: Fix missing initialization in find_trampoline_placement() 
[ Upstream commit c96e8483cb ]

Gustavo noticed that 'new' can be left uninitialized if 'bios_start'
happens to be less or equal to 'entry->addr + entry->size'.

Initialize the variable at the begin of the iteration to the current value
of 'bios_start'.
