[PATCH] ata: libata-core: fix sloppy parameter type in ata_exec_internal[_sg]()

[Sergey Shtylyov <s.shtylyov@omp.ru>]

Make the 'timeout' parameter to ata_exec_internal_sg() *unsigned int* as
msecs_to_jiffies() that it calls takes just *unsigned int* for the time in
milliseconds. Then follow the suit with ata_exec_internal(), its only
caller; also fix up ata_dev_set_feature(), the only ata_exec_internal()'s
caller  that explicitly passes *unsigned long* variable for timeout...

Found by Linux Verification Center (linuxtesting.org) with the SVACE static
analysis tool.
