Niklas Cassel e164562978 PCI: endpoint: Fix find_first_zero_bit() usage ...

[ Upstream commit 35ad61921f ]

find_first_zero_bit()'s parameter 'size' is defined in bits,
not in bytes.

Calling find_first_zero_bit() with the wrong size unit
will lead to insidious bugs.

Fix this by calling find_first_zero_bit() with size BITS_PER_LONG,
rather than sizeof() and add missing find_first_zero_bit() return
handling.
