x86: entry_32.S fix compile warnings - fix work mask bit width

Fix:

arch/x86/kernel/entry_32.S:446: Warning: 00000000080001d1 shortened to 00000000000001d1
arch/x86/kernel/entry_32.S:457: Warning: 000000000800feff shortened to 000000000000feff
arch/x86/kernel/entry_32.S:527: Warning: 00000000080001d1 shortened to 00000000000001d1
arch/x86/kernel/entry_32.S:541: Warning: 000000000800feff shortened to 000000000000feff
arch/x86/kernel/entry_32.S:676: Warning: 0000000008000091 shortened to 0000000000000091

TIF_SYSCALL_FTRACE is 0x08000000 and until now we checked the
first 16 bits of the work mask - bit 27 falls outside of that.

Update the entry_32.S code to check the full 32-bit mask.
