ARM: 7088/1: entry: fix wrong parameter name used in do_thumb_abort

Browse Source 
Commit be020f8618, "ARM: entry: abort-macro: specify registers to be
used for macros", while replacing register numbers with macro parameter
names, mismatched the name used for r1. For me, this resulted in user
space built for EABI with -march=armv4t -mtune=arm920t -mthumb-interwork
-mthumb broken on my OMAP1510 based Amstrad Delta (old ABI and no thumb
still worked for me though).

Fix this by using correct parameter name fsr instead of mismatched psr,
used by callers for another purpose.
